Pin Functions

PIN I/O DESCRIPTION
NAME NO.
DDA DBV
DRAIN 8 4 O Drain of the internal switch.
N/C 2 — — Not internally connected.
N/C 6
N/C 7
VIN 1 3 I Positive power supply for the device.
VS 4 2 I/O Source of the internal switch. This pin is also the device floating ground.
RSET 3 1 I/O A resistor connected between the RSET pin and the VIN pin sets the rising threshold to open the switch.
RSNS 5 5 I/O A resistor connected between the RSNS pin to system ground senses the VS voltage relative to system ground.
Exposed Themal Pad Connect to VS pin directly beneath the device.
