Manufacturer: Zentrum Mikroelektronik Dresden

Overview: Data Sheet Rev. 1.00 / April 2012 ZSSC1856 Intelligent Battery Sensor IC ZSSC1856 Intelligent Battery Sensor IC.

General Description

The ZSSC1856 is a dual-channel ADC with an embedded microcontroller for battery sensing/management in automotive, industrial, and medical systems.

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.
