LTC2966 Dual Voltage Monitor Design Tool

Export CSV »

The LTC2966 is a low current, high voltage dual channel voltage monitor. Internal high value resistors sense the input monitor pins providing a compact and low power solution for voltage monitoring. Each channel includes two comparator reference inputs (INH/INL) to allow configuration of a high and low threshold using an external resistive divider biased from the on-chip reference. Range selection pins are provided for each channel to set the internal resistive dividers for 5x, 10x, 20x and 40x scaling. The thresholds are scaled according to the range selection settings. Additionally, either INH or INL can be grounded to enable built-in hysteresis. Polarity selection pins allow each output to be inverted. The outputs are 100V capable and include a 500k pull-up resistor to an internal supply. Two common threshold configurations are:

Two common threshold configurations are:

3-Resistor Configuration:
Uses 3 resistors to set the V(rise) and V(fall).

2-Resistor Configuration
Uses 2 resistors to set the V(rise) and V(fall).
