36V Nano-Current
Two-Input Voltage Monitor
The LT C
®
2960 is a nano-current, high voltage two-input
voltage monitor,
ideally suited for multicell battery ap-
plications. External
resistive dividers configure custom
comparator thresholds. The supervisory circuit monitors
the ADJ input and pulls the RST output low when the input
drops below threshold. A reset timeout period delays the
return of the RST output to a high state when the input
rises above the threshold. The spare comparator allows
voltage conditions to be detected with either a non-inverting
input, IN
+
(LTC2960-1/LTC2960-3) or an inverting input,
IN
–
(LTC2960-2/LTC2960-4). A manual reset (MR) input
is provided for external activation of the reset output.
Other options provided on the LTC2960-1/LTC2960-2 in
-
clude a reset timeout period select pin, RT, to select between
15ms or 200ms reset timeout periods. The LTC2960-3/
LTC2960-4 have a fixed 200ms reset timeout period. The
RST and OUT outputs are available with active pull-up cir
-
cuits to an
output logic supply pin (LTC2960-3/LTC2960-4)
or 36V open-drain outputs (LTC2960-1/LTC2960-2).
