ZSSC1956

Intelligent Battery Sensor IC ZSSC1956 Datasheet Brief Description The ZSSC1956 IC is a dual-channel analog-to-digital converter (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 customerspecific 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 wakeup conditions. The ZSSC1956 is optimized for ultralow power consumption and draws only 100µA or less in Low-Power Mode. Features High-precision 24-bit sigma-delta ADC (18-bit with no missing codes); sample rate: 1Hz – 16...
