Description
This pin is the source of the internal power FET and the output terminal of the IC.
DO NOT CONNECT, The pin must be float.
A resistor between this pin and the Source pin sets the overload and short circuit
current limit levels.
The Enable/Fault pin is a tri-state, bi-directional interface. It can be used to enable the
output of the device by floating the pin, or disable the chip by pulling it to ground
(using an open drain or open collector device). If a thermal fault occurs, the voltage
on this pin will go to an intermediate state to signal a monitoring circuit that the device
is in thermal shutdown.
The internal dv/dt circuit controls the slew rate of the output voltage at turn on. It has
an internal capacitor that allows it to ramp up over the period of 1.5ms. An external
capacitor can be added to this pin to increase the ramp time. If an additional time
delay is not required, this pin should be left open.
Negative Input Voltage to the Device. This is used as the internal reference for the IC.
Positive input voltage to the device (Exposed Pad).
