Data Acquisition System Basis Chip
ZSSC1750 / ZSSC1751
Datasheet
Brief Description
The ZSSC1750 and ZSSC1751 are System Basis Chips (SBCs) with a dual-channel ADC for battery sensing/management in automotive, industrial, and medical systems.
The ZSSC1750 and ZSSC1751 feature an SPI interface; in addition, the ZSSC1750 has an integrated LIN 2.
1 transceiver.
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 ...
