BQ77905EVM-707 (TEXAS INSTRUMENTS)

The BQ77905EVM-707 from Texas Instruments is a evaluation module (EVM) for the bq77905 3-5S low power protector for lithium-ion cells. The EVM includes one bq77905 and FETs to control current in a configuration typical for switching current in a lithium-ion battery pack. The circuit module includes one bq77905 integrated circuit (IC), a sense resistor, thermistor, two CSD18534Q5A FETs and all other on-board components necessary to switch charge and discharge current. The circuit module connects between a 'battery' source and a 'pack' load. In addition to the current and voltage applied to the module the user can remove on-board jumpers to simulate over or under-temperature conditions to observe FET control under different charge and discharge conditions.
