TYPICAL PERFORMANCE CHARACTERISTICS
DIS (Pin 8/Pin 1, LTC2912-2): Output Disable Input.
Disables the OV and UV output pins. When DIS is pulled
high, the OV and UV pins are not asserted except during a
UVLO condition. Pin has a weak (2μA) internal pull-down
to GND. Leave pin open if unused.
Exposed Pad (Pin 9, DDB Package): Exposed Pad may
be left open or connected to device ground.
GND (Pin 5/Pin 4): Device Ground.
LATCH (Pin 8/Pin 1, LTC2912-1, LTC2912-3): OV/OV
Latch Clear/Bypass Input. When pulled high, OV/OV latch

is cleared. While held high, OV/OV has a similar delay and
output characteristic as UV.
OV (Pin 6/Pin 3, LTC2912-1, LTC2912-2): Overvoltage
Logic Output. Asserts low when the VL input voltage is
above threshold. Latched low (LTC2912-1). Held low for
programmed delay time after VL input is valid (LTC2912-2).
Pin has a weak pull-up to V
using an external pull-up. Leave pin open if unused.
