PIN FUNCTIONS
TYPICAL PERFORMANCE CHARACTERISTICS
Exposed Pad (DFN Only): Exposed Pad may be left fl oating
or connected to device ground.
GND: Device ground.
MR: Manual Reset Input. Attach a pushbutton switch
between this input and ground. A logic low on this input
pulls RST low. When the MR input returns to logic high,
RST returns high after 200ms. Tie to V
PFO: Power-Fail Output. PFO pulls low when V
below the power-fail threshold. The power-fail thresh-
old is above the confi gured falling reset threshold by a
pre-determined margin. PFO is released when V
above the power-fail threshold by 2.5%. PFO is available
with open-drain (LTC2935-1/LTC2935-3) or active pull-up
(LTC2935-2/LTC2935-4) outputs. Leave open if unused.

RST: Reset Output. RST pulls low when V
reset threshold. RST is released 200ms after V
the reset threshold plus 5% hysteresis. RST is available
with open-drain (LTC2935-1/LTC2935-3) or active pull-up
(LTC2935-2/LTC2935-4) outputs. Leave open if unused.
S2, S1, S0: Threshold Selection Inputs. Tie to GND or
