Function
1
GND
Ground pin
2 dv/dt
Internal NMOS power device turn-on time adjustment pin:
If this pin is is left unconnected, the internal capacitor ensures the turn-on ramp is over a
period of 2ms typical. If an additional delay is required, connect a capacitor from this pin to the
ground.
3 Enable/Fault
Tri-state bi-directional interface pin:
The output can be disabled by pulling this pin to ground through an open drain or an open
collector. Additionally, this pin output goes to an intermediate state to indicate that the device
is in thermal shutdown state. This pin can also be connected together with other NIS5132
devices to cause a system-wide simultaneous shutdown during thermal events.

LIMIT
Current limit setting pin:
A resistor between Source pins and this pin sets the overload and short-circuit current limit
thresholds.

6 to 10
Source
The internal NMOS power device’s Source pins:
These pins are the Source of internal power device and also the output terminal of the
electronic fuse
