PIN FUNCTIONS
TYPICAL PERFORMANCE CHARACTERISTICS
ADJ: Reset Threshold Adjustment Input. Tie to resistive
divider between monitored voltage and GND to confi gure
desired reset threshold. See the Applications Information
section for details. Tie to V
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 push-button 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 the reset timer has expired. Tie to
V
PFI: Power-Fail Threshold Adjustment Input. Tie to
resistive divider between monitored voltage and GND
to configure desired power-fail threshold. See the
Applications Information section for details. Tie to V
GND if unused.
CC
if unused.

PFO: Power-Fail Output. PFO pulls low when monitored
voltage falls below the power-fail (PFI) threshold. PFO
is released when the PFI voltage rises above the power-
fail threshold by 2.5%. PFO is available with open-drain
(LTC2934-1) or active pull-up (LTC2934-2) outputs. Leave
open if unused.
RST: Reset Output. RST pulls low when monitored volt-
age falls below the reset threshold. RST is released after
monitored voltage exceeds the reset threshold plus 5%
hysteresis and after reset timer has expired. RST is available
with open-drain (LTC2934-1) or active pull-up (LTC2934-2)
outputs. Leave open if unused.
RT: Reset Timeout Selection Input. Tie to GND or V
desired reset timeout. Tie low for 15ms delay or high for
200ms delay.
