The BQ77PL900EVM-001 is a complete evaluation system for the bq77PL900, a five to ten cell Li ion battery protection and AFE integrated circuit. The circuit module includes 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.
● 5, 6, 7, 8, 9, or 10 series cell primary protection
● PMOS FET drive for charge and discharge FETs
● Populated circuit module for quick setup
● PC software and interface board for easy evaluation
● Connections for attaching a the circuit module to a host system
● Capable of operation with 1mR sense resistor
● Low supply current of 450µA typical
●The bq77908A circuit module may become hot during operation due to dissipation of heat. Avoid contact with the board. Follow all applicable safety procedures applicable to your laboratory.
