Battery Management from Our Award-Winning Solutions Enable Energy-Efficient Systems

ZMDI’s Battery Monitoring ICs Enable Energy Efficiency Due to the urgent global need to reduce environmental pollution and to meet governmental 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 ultralow 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.

Applications for ZMDI Battery Management ICs • Lead-acid battery monitoring • Battery monitoring for energy storage; e.g., in photovoltaic installations • Intelligent sensors and sensor interfaces • Electric energy measurement and monitoring

Battery Monitoring ICs with Internal and External Microcontrollers ZMDI offers two product lines for battery monitoring 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.

Key Features Intelligent Battery Sensor ICs • Wide operating temperature: -40°C to +125°C • High-Precision 24-bit sigma-delta ADC (18 bits with no missing codes) • On-chip voltage reference (5ppm/K) • External or internal, factory-calibrated temperature sensor • Small PQFN packages: 5x5mm or 6x6mm • 32-bit ARM® Cortex™-M0* microcontroller

Highly Efficient Analog ICs for Charge Management • ZSPM4121 Under-Voltage Load Switch • ZSPM4521 High-Efficiency Charger for Li-Ion Batteries with Photovoltaic Sources • ZSPM4523 High-Efficiency Solar PV MPPT Regulator for Super Capacitor Systems • ZSPM4551 High-Efficiency Li-Ion Battery Charger ARM© and Cortex™ are trademarks of ARM, Ltd.

ZSSC1750/51

Data Acquisition System Basis Chip (SBC)

Brief Description

Benefits

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 stateof-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

ZSPM4121

Under-Voltage Load Switch for Smart Battery Management

Brief Description

Features

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 increments to support a wide range of applications in consumer, 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-channel 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 overcurrent 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

    

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
