The ZSSC1750 is a System Basis Chip (SBC) with a dual-channel ADC for battery sensing/management in automotive, industrial, and medical systems. The ZSSC1750 features an SPI interface. 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 state-of-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 is optimized for ultra-low power consumption drawing only 60μA or less in this mode.
