SLVSHR0 May 2025 TPS2HCS08-Q1
PRODUCTION DATA
The TPS2HCS08-Q1 provides a temperature measurement for each of the power MOSFETs through the 10-bit ADC.
The FET temperature sense function is disabled by default. To enable the FET temperature sense function for each channel it needs to be globally enabled in the ADC_CONFIG register through the ADC_TSNS_DIS bit.
The conversion equation for the FET temperature measurement is detailed in Equation 11. The ADC measurement result will be available in the ADC_RESULT_CHx_T register. The TSNS_RDY_CHx bit is set to 1 if a new ADC conversion result exists since the register was last read. If any of the channels are in the I2T loop (I2T_MOD_CHx = 1), the FET temperature measurement, if enabled, will be disabled for all the channels and the TSNS_RDY_CHx bit will be 0. Once the channel(s) exit the I2T loop (I2T_MOD_CHx = 0), then the FET temperature measurement will be automatically re-enabled if previously enabled before the I2T event.
