DETAILED DESCRIPTION (continued)

STAT: STAT indicates the status of the GATE pin drive. The internal weak pull-up drives STAT high when

tied together to desensitize turnoff. If STAT is externally pulled low while the pin would otherwise be high, the

turn-off threshold is shifted negative from the RSET programmed value.

UV, OV, PG: These signals are used to monitor an input voltage for proper range. PG sinks current to GND if

A high input on OV causes GATE to be driven low. UV does not effect the MOSFET operation. This permits OV

to be used as an active-high disable.

OV and UV should be connected to ground when not used, and PG may be left open. Multiple PG pins to be

wire ORed using a common pull-up resistor.

A 0.01-

µF bypass capacitor, or 10-Ω and a 0.0 1-µF filter, is recommended because charge pump currents are
