Module Enable and Thermal Shutdown
6.1
Description
With the enable pin the device can be set in off-state reducing the current consumption to less than 2A.
The enable function features an integrated pull down resistor which ensures that the IC is shut down and the power
switch is off in case the pin EN is left open.
The integrated thermal shutdown function turns the power switch off in case of overtemperature. The typ. junction
shutdown temperature is 175°C, with a min. of 160°C. After cooling down the IC will automatically restart
operation. The thermal shutdown is an integrated protection function designed to prevent IC destruction when
operating under fault conditions. It should not be used for normal operation.
