TYPICAL PERFORMANCE CHARACTERISTICS
DIS (Pin 8, LTC2913-2): 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. DIS has a weak (2µA) internal pull-down to
GND. Leave DIS open if unused.
Exposed Pad (Pin 11, DFN Package): Exposed Pad may
be left open or connected to device ground.
GND (Pin 5): Device Ground.

LATCH (Pin 8, LTC2913-1): OV Latch Clear/Bypass Input.
When pin is pulled low, OV is latched when asserted. When
pulled high, OV latch is cleared. While held high, OV has
the same delay and output characteristics as UV.
OV (Pin 6): Overvoltage Logic Output. Asserts low when
either VL input voltage is above threshold. Latched low
(LTC2913-1). Held low for programmed delay time after
both VL inputs are valid (LTC2913-2). OV has a weak pull-
up to V
pull-up. Leave OV open if unused.
