PIN DESCRIPTION

NAME
TYPE
FUNCTION
Enable and Under-Voltage Lockout Input. Asserting EN/UVLO pin high enables the device. As a
UVLO pin, the UVLO threshold is programmed by an external resistor divider. This pin cannot
be left floating.
1
EN/UVLO
Analog Input
Over-Voltage Lockout Pin. The over-voltage lockout threshold is programmed by the resistor
divider from the power supply to the OVLO terminal to GND. The device is enabled when this
pin is tied to low level. This pin cannot be left floating.
Power Good Indication (SGM2536Px). This is an open-drain pin, when the internal channels of
the chip are all turned on and the PGTH signal value is higher than the set value, the pin is set
to high level.

Supply Good Indication (SGM2536Fx). This is an open-drain pin, when the input voltage is
within the valid range and the surge has finished, this pin goes high.

Power
Soft-Start Pin. The capacitor between SS and GND pins will set the slew rate according to the
application requirements. When this pin is left floating, the device will start up at the fastest rate.

GND.
Programming Current Limit Pin. A resistor between this pin and GND sets the overload and
short-circuit current limit levels. Do not float this pin.
Analog Output
Place a capacitor between this pin and GND can set the over-current blanking time, at this
stage, the output current value can temporarily exceed the internally set current limit value (but
not exceed the fast-trip threshold). After this time, the device will take action if it is still in
over-current state. Leaving this pin open will provide the fastest response to an over-current
event.
