BQ77PL900EVM-001 evaluation module is a complete evaluation system for the bq77PL900, a five- to ten-cell Li-ion battery protection and AFE integrated circuit. The EVM includes one bq77PL900 circuit module, an EV2300 PC interface board, an interface cable, a PC USB cable, and Windows™-based PC software. The circuit module includes one bq77PL900 integrated circuit (IC), sense resistor, power FETs and all other onboard components necessary to protect the cells from overcharge, over discharge, short circuit, and over current discharge in 5 to 10 series cell Li-ion or Li-polymer battery packs. The circuit module connects directly across the cells in a battery. With the EV2300 interface board and software, the user can read the bq77PL900 data registers, program the IC protection limits, and evaluate the overall functionality of the bq77PL900 solution under different operational conditions.
The EV2300 is a USB-based interface board for a PC that can be used to evaluate battery fuel gauge circuits designed with Texas Instruments' ICs. The EV2300 has connections on it for a USB cable and also accepts inputs from a battery fuel gauge circuit's communication port (SMBus or HDQ). By running the appropriate PC software for the corresponging fuel gauge IC, the EV2300 interface board allows the user to evaluate the battery fuel gauge circuit.
