EVM is a complete evaluation system for low-power protector for lithium-ion cells

The Texas Instruments BQ77915EVM-014 EVM is a total evaluation system for the BQ77915 3-series to 5-series low-power protector for lithium-ion cells. The EVM includes one BQ77915 and FETs to control current in a configuration typically found for switching current in a lithium-ion battery pack. The circuit module comprises one BQ77915 IC, a thermistor, a sense resistor, two FETs, and all other onboard components needed to switch charge and discharge current. The circuit module connects within a battery source and a pack load. As well as the current and voltage applied to the module, the user can separate onboard jumpers to simulate overtemperature or undertemperature conditions to observe FET control under various charge and discharge conditions. Balancing of unmatched cells can also be achieved on the module.
