Data Sheet Rev. 1.00 / April 2012 ZSSC1856 Intelligent Battery Sensor IC ZSSC1856 Intelligent Battery Sensor IC Brief 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. An integrated flash memory is provided for customer-specific software; e.g., dedicated algorithms for calculating the battery state. During Sleep Mode (e.g., engine off), the system makes periodic measurements to monitor the discharge of the battery.
