active to reduce standby current. When an over-temperature
condition is detected, the MOSFET is immediately turned
off and the load bleed is activated.
junction temperature decreases to a safe operating
temperature as dictated by the thermal hysteresis. Upon
exiting a thermal shutdown state, and if EN remains active,
the MOSFET will be turned on in a controlled fashion with
the normal output turn-on delay and slew rate.
The part comes out of thermal shutdown when the
