1
PG
Power Good Output This is an active high power good output signal. This pin is referenced to VIN.
(Active High)
2
PG
Power Good Output This is an active low power good output signal. This pin is referenced to VIN.
(Active Low)
3
VOUT
Voltage Output
This pin is the drain of the internal Power MOSFET and supplies a current limited voltage
to the load.
4
VIN
Negative Supply This is the most negative power supply input. All pins except DISABLE are referenced
Voltage Input
to this input.
5
VPWR
Positive Supply This is the most-positive power supply input. The load connects between this pin and the
Voltage Input
VOUT pin.
6
DISABLE Disable Input Control This pin is used to easily disconnect or connect the load from the main power line by
disabling or enabling the 34653. It can also be used to reset the fault conditions that
cause a “Power No Good” signal. This pin is referenced to VPWR.
7
ILIM
Current Limit Control This pin is used to set the overcurrent limit during normal operation.
8
ICHG
Charging Current This pin is used to set the load’s input capacitor charging current limit, hence limiting the
Limit Control
inrush current to a known constant value.
