LTC2960

36V Nano-Current

Two-Input Voltage Monitor

FeaTures

DescripTion

The

LTC

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,

–

(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).
