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 threshold
is 150mV above the confi gured falling reset threshold.
PFO is released when V
threshold by 2.5%. PFO is available with open-drain
(LTC2935-1) or active pull-up (LTC2935-2) outputs. Leave
open if unused.

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