7.3.10.1 Thermal Warning (HOT) and Thermal Shutdown (TSD)

DLPA2000 continuously monitors the junction temperature and issues a HOT interrupt if temperature exceeds the HOT threshold. If the temperature continues to increase above the thermal shutdown threshold, all rails are disabled and the TSD bit in the INT register is set. After the temperature drops below its threshold, the system recovers and waits for the DPP to resend the DMD_EN bit.
