SLUUAV7C December 2013 – November 2022 BQ40Z50 , BQ40Z50-R2
The PTC interface is designed to work with a specific PTC thermistor. The thermistor must have a 10-kΩ typical resistance over the normal operating temperature range and the resistance must be greater than 1.2 MΩ at the PTC trip temperature. The muRata PRF18BA103QB1RB thermistor will work with this device.
The EVM has a 10-kΩ resistor installed on the PTC footprint.
The PTC function can be disabled by connecting PTC and PTCEN to VSS.
