The TPS206xA monitors the operating temperature of both power distribution switches with individual thermal sensors. The junction temperature of each channel rises during an overcurrent or short-circuit condition. When the die temperature of a particular channel rises above a minimum of 135°C in an overcurrent condition, the internal thermal sense circuitry disables the individual channel in overtemperature to prevent damage. Hysteresis is built into the thermal sensor and re-enables the power switch individually after it has cooled approximately 10°C. The power switch cycles on and off until the fault is removed. This topology allows one channel to continue normal operation even if the other channel is in an overtemperature condition. The open-drain overcurrent flag ( OCx) is asserted (active low) corresponding to the channel that is in an overtemperature or overcurrent condition.
