Description

Positive Supply Input Pin (VCC). A UVLO circuit resets the device when a low supply voltage is detected. GATE is

held off when the supply is below UVLO. No sequencing is required.

Positive Current Sense Input Pin (SENSE+). This pin connects to the main supply input. A sense resistor between

the VCC/SENSE+ pin and the SENSE− pin sets the analog current limit. The hot swap operation of the ADM1270

controls the external FET gate to maintain the sense voltage (VSENSE+ − VSENSE−).

Reverse Protection FET Gate Driver Output. Connect this pin to the gate of the external reverse polarity protection

P-channel FET for low voltage drop operation.

Exposed Pad. The exposed pad is located on the underside of the LFCSP package. Solder the exposed pad to the

printed circuit board (PCB) to improve thermal dissipation. The exposed pad can be connected to ground.
