Thermal ShutDown(TSD: overheat protection) is the function that MOSFET inside is shut down when the junction temperature of eFuse IC rises to the set value.
Auto-retry type is that MOSFET turns on again when MOSFET shuts down and the junction temperature drops to the setpoint.
Latch type is that MOSFET is kept shut down after eFuse IC junction temperature has risen and TSD has been activated. Releasing the latch is performed by applying a reset by EN/ UVLO signal.
The figure below shows the operation image of the auto-retry type TSD function (TCKE8 series).
