Integrated Device Technology Intelligent Battery Sensor IC ZSSC1956BA3R

The ZSSC1956 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 input 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 is off), the system makes periodic measurements to monitor the discharge of the battery. Measurement cycles are controlled by the software and include various wake-up conditions. The ZSSC1956 is optimized for ultra-low power consumption and draws only 100
