Ground Pin
The internal dv/dt circuit controls the slew rate of the output voltage at turn-on. The internal
capacitor allows a ramp-up time of around 1ms. An external capacitor can be added to this
pin to increase the ramp time. If an additional capacitor is not required, this pin should be
left open.
The enable/fault pin is a tri-state, bi-directional interface. During normal operation the pin
must be left floating, or it can be used to disable the output of the device 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
monitor circuit that the device is in thermal shutdown. It can be connected to another device
of this family to cause a simultaneous shutdown during thermal events.
A resistor between this pin and the Source pin sets the overload and short circuit current
limit levels.
Not connected
Connected to the Source of the internal power MOSFET and to the output terminal of the
fuse
Exposed pad. Positive input voltage must be connected to Vcc.
