Each channel has its own temperature sensor. If the temperature at the channel exceeds the thermal shutdown
temperature T
to reactivate the channel, the temperature at the output must drop by at least the thermal hysteresis ∆ T
over temperature latch must be cleared by SPI command HWCR.CTL = 1. All over temperature latches are cleared
by SPI command HWCR.CTL = 1.
Figure 11
Additionally, channels 0, 1, 2, 3, 4 have their own dynamic temperature sensors. The dynamic temperature sensor
improves short circuit robustness by limiting sudden increases in the junction temperature. The dynamic
temperature sensor turns off the channel if its sudden temperature increase exceeds the dynamic temperature
sensor threshold ∆ T
