PIN FUNCTIONS
LTC2960
ADJ: Reset Threshold Adjustment Input. Tie to resistive
divider to configure desired reset threshold.
DV
for setting the logic swing of the RST and OUT outputs.
Useful for interfacing with logic voltages different from
V
allows OUT and RST to act as open drain outputs.
Exposed Pad (DFN Only): Exposed pad may be left floating
or connected to device ground.
GND: Device ground.
IN
Input. Tie to resistive divider to configure required thresh-
old. Tie to GND if unused.
IN
Input. Tie to resistive divider to configure required thresh-
old. Tie to GND if unused.
MR: Manual Reset Input. Attach a push-button switch or
logic signal 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 a reset timeout period
has expired. Leave open if unused.

RST: Reset Output. Pulls low when monitored voltage falls
below the reset (ADJ) threshold. RST is released after
monitored voltage exceeds the reset threshold plus 2.5%
hysteresis and after reset timeout period has expired. For
the LTC2960-3/LTC2960-4, RST is driven to DV
logic high. RST is open drain if DV
open if unused.
RT: (LTC2960-1/LTC2960-2) Reset Timeout Period Se-
lection Input. Tie to GND for 15ms delay. Tie to V
200ms delay.

anteed. Bypass V
