LTC2960 36V Nano-Current Two Input Voltage Monitor Features n n n n n n n n DESCRIPTION The LTC®2960 is a nano-current, high voltage two input voltage monitor, ideally suited for multicell battery applications. External resistive dividers configure custom parator 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 parator 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 include 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 circuits to an output logic supply pin (LTC2960-3/LTC2960-4) or 36V open-drain outputs (LTC2960-1/LTC2960-2).
