V CC1
Description
Supply Voltage 1. Either V CC1 or V CC2 must be greater than the UVLO to enable external
FET Drive.

SETV
Chip Ground Pin.
Sequenced Threshold Set. Connect to an external resistor divider to set the V CC1
threshold that enables GATE turn-on. The internal reference is 0.618 V.

EN
Active-High Enable. GATE drive is enabled t DELAY after EN is driven high. GATE drive is
immediately disabled when EN is driven low. Connect this pin to the higher of V CC1 or
V CC2 if not used. EN is internally identical to SETV (0.618 V threshold) and, therefore, can
be used as a second supply monitor, enabling two supplies to be validated before
sequencing begins.

SETD
GATE Delay Set Input. Connect an external capacitor from SETD to GND to adjust the
delay from SETV > V TH to GATE turn-on. t DELAY (s) = 2.652 × 10 6 × C SET (F).

GATE
GATE Drive Output. GATE drives an external N-channel FET to connect V CC2 to the load.
GATE drive enables t DELAY after SETV exceeds V TH and ENABLE is driven high. GATE drive is
immediately disabled when SETV drops below V TH or ENABLE is driven low. When
enabled, an internal charge pump drives GATE above V CCX to fully enhance the external
N-channel FET.

V CC2
Supply Voltage 2. Either V CC1 or V CC2 must be greater than the UVLO to enable the
external FET Drive.
