bq76200 High Voltage Battery Pack Front-End
Charge/Discharge High-Side NFET Driver Evaluation
Module
This evaluation module (EVM) is a complete evaluation system for the bq76200 High Voltage Battery
Pack Front-End Charge/Discharge High-Side NFET Driver. The EVM includes one bq76200 and FETs to
control current in a configuration typical for switching current in a lithium-ion battery pack. The circuit
module includes one bq76200 integrated circuit (IC), two CSD19351Q5A FETs, and all other onboard
components necessary to switch charge, discharge, and precharge current and to monitor the output pack
voltage. The circuit module connects between a "battery" source and a "pack" load. With the on-board
jumpers or external control, the user can switch the FETs to evaluate the overall functionality of the
solution under different charge and discharge conditions.
