Overview
Description
The ISL73141BMREFEVKIT1Z evaluation kit demonstrates the ISL73141SEH 14-bit SAR ADC in an 8-cell battery voltage monitoring application. Monitoring of the lithium battery cell voltages is critical to protect the battery against undervoltage and overvoltage conditions.
The ISL73141BMREFEV1Z 8-cell battery monitor main board leverages our radiation hardened ISL70444SEH quad 40V rail-to-rail op amps, ISL71830SEH 16-channel multiplexer, ISL73141SEH 14-bit 1000ksps SAR ADC paired with an ISL71091SEH40 voltage reference, to monitor each of the 8-cell voltages of the battery. The evaluation kit also comes with a VBAT 8-cell resistor divider (BMSVOLTDIV8REFEV1Z) board to emulate an 8-cell battery stack.
