ZMDI’s Battery Monitoring ICs Enable Energy Efficiency

Due to the urgent global need to reduce environmental pollution and to meet governmen-tal regulations limiting maximum harmful emission from vehicles, automotive companies are increasing their efforts to introduce features aimed towards reducing fuel consumption.One of these highly effective fuel saving features is the start-stop system, which automatically shuts down and restarts the engine as needed to reduce the amount of time the engine spends idling, thereby reducing fuel consumption and emissions by as much as 5 to10 percent. In order to ensure a safe re-start of the engine once it has been turned off, precise information on the charge condition of the starter battery is essential.ZMDI’s battery monitoring ICs accurately determine the charge condition of the battery based on inputs including charge and discharge currents, battery voltage, temperature, and aging. Both voltage and current are measured with two highly linear, synchronous 24-bit analog-to-digital converters.Measuring charge and discharge currents is particularly challenging as the battery monitoring IC must be capable of precisely measuring milliampere currents when the engine is turned off and up to more than one thousand amperes when the engine is started. ZMDI’s battery monitoring ICs can achieve this requirement by means of a shunt-resistor-based current measurement technique combined with a highly dynamic embedded programmable gain amplifier.Another challenging requirement is for ultra-low power consumption in standby mode, for example when a vehicle is parked. The battery monitoring IC must continue to monitor the battery’s state even when the engine is turned off. In this standby mode, our battery monitoring ICs typically consume only 55 to 60 μA.

ZMDI offers two product lines for battery monitor-ing ICs: one for external microcontrollers and a more advanced line with an integrated 32-bit ARM© Cortex™ based microcontroller.*Our leading-edge ICs with an internal microcontroller are preferred for small form-factor, standalone intelligent battery monitoring systems. Our battery monitoring ICs for use with external microcontrollers are preferred for solutions that are embedded in systems that already contain a microcontroller or where one master controller controls several battery monitoring slaves, such as in multi-battery applications or systems requiring additional safety via redundant measurement of battery current.ZMDI’s ICs with an internal microcontroller offer effective intellectual property safeguarding for customer software by employing copy protection for the user’s firmware on the chip.

Brief Description The ZSSC1750 and ZSSC1751 are System Basis Chips (SBCs) with a dual-channel ADC for battery sensing/management in automotive, industrial, and medical systems. The ZSSC1750 and ZSSC1751 feature an SPI interface; in addition, the ZSSC1750 has an integrated LIN 2.1 transceiver. One of the two input channels measures the battery current IBAT via the voltage drop at the external shunt resistor. The second channel measures the battery voltage VBAT and the temperature. By simultaneously measuring VBAT and IBAT, it is possible to determine dynamically the internal resistance of the battery, Rdi, which is correlated with the state-of-health (SOH) of the battery. By integrating IBAT, it is possible to determine the state-of-charge (SOC) and the state-of-function (SOF) of the battery. During Sleep Mode, the system makes periodic measurements to monitor the discharge of the battery. Measurement cycles are controlled by user software and include various wake-up conditions. The ZSSC1750/51 is optimized for ultra-low power consumption drawing only 60µA or less in this mode.

ZSPM4121 Under-Voltage Load Switch for Smart Battery Management

© 2013 Zentrum Mikroelektronik Dresden AG — Rev. 1.01 — February 7, 2013. All rights reserved. The material contained herein may not be reproduced, adapted, merged, translated, stored, or used without the prior written consent of the copyright owner. The information furnished in this publication is subject to changes without notice.


Brief Description The ZSPM4121 battery management load switch can be used to protect a battery from excessive discharge. It actively monitors the battery voltage and disconnects the battery from the load if the battery drops below a set voltage threshold. When the input battery voltage reaches 500mV above the set voltage threshold, the load switch turns on and connects the battery to the load. The 500mV hysteresis between the Off Mode and the On Mode prevents intermittent operation. The voltage threshold (VTHRESH) can be programmed at manufacturing to a customer-selected set point in the voltage range of 1.2V to 4.2V in 100mV incre-ments to support a wide range of applications in con-sumer, medical, portable, and industrial applications. This device has ultra-low quiescent current, which makes it ideal for battery-powered applications. Typical quiescent current is 100pA in the Off Mode and 70nA in the On Mode. The ZSPM4121 includes a slew rate control P-chan-nel load switch, over-current protection, and an open-drain power indicator pin (NPG). The slew-rate controlled turn-on characteristic prevents inrush current and voltage droop on the voltage. The over-current limit protects the device in case of an overload, short-circuit, or ground fault event.

Benefits Best-in-class ultra-low quiescent current in

Off Mode: 100pA (typical) Ultra-low quiescent current in On Mode: 70nA

(typical) Accurate on/off voltage threshold Low Rds(on): 175mΩ (typical) @ 5V

Features Threshold voltage options of 1.2V to 4.2V in

100mV steps (factory programmed) Wide input voltage range: 1.2V to 5.5V Supervisory over-current limit shutdown: (3A) Low drop-out disconnect from VCC to loads Controlled turn-on slew rate 500mV Off Mode to On Mode hysteresis

ZSPM4521

Brief Description The ZSPM4521 is a DC/DC synchronous switching lithium-ion (Li-Ion) battery charger with fully inte-grated power switches, internal compensation, and full fault protection. It uses a temperature-indepen-dent photovoltaic maximum power point tracking (MPPT) function to optimize power output from the source during Full-Charge Constant-Current (CC) Mode. Its switching frequency of 1MHz enables the use of small filter components, resulting in smaller board space and reduced bill-of material costs. During Full-Charge Constant-Current Mode, the duty cycle is controlled by the MPPT regulator. Once the battery’s termination voltage is reached, the regula-tor operates in Constant Voltage Mode. In this mode, the ZSPM4521 modulates the charging current until the battery reaches full charge. When the regulator is disabled (the EN pin is low), the device draws 10µA (typical) quiescent current (Disabled Mode). The ZSPM4521 includes supervisory reporting through the NFLT (inverted fault) open-drain output to interface other components in the system. Device programming is achieved by an I²C™* interface through the SCL and SDA pins.

Benefits Up to 1.5A of continuous output current in Full-

Charge Constant Current (CC) Mode High efficiency – up to 92% with typical loads

ZSPM4523

Brief Description The ZSPM4523 is a DC/DC synchronous switching super capacitor charger with fully integrated power switches, internal compensation, and full fault pro-tection. It uses a temperature-independent photo-voltaic maximum power point tracking (MPPT) calcu-lator to optimize power output from the source during Full-Charge Mode. Its 1MHz switching frequency allows using small filter components, which results in smaller board space and reduced bill-of-material costs. In Full-Charge Mode, the duty cycle is controlled by the MPPT function. Once the termination voltage is reached, the regulator operates in Constant Voltage Mode. When the regulator is disabled (the EN pin is low), the device draws 10µA (typical) quiescent current from VOUT. The ZSPM4523 integrates a wide range of protec-tion circuitry, including input supply under-voltage lockout, output over-voltage protection, current limiting, and thermal shutdown. The ZSPM4523 includes supervisory reporting via the NFLT (Inverted Fault) open-drain output to interface other components in the system. Device programming is achieved by the I²C™* interface through the SCL and SDA pins.
