3.3 Comparator

The INA310 incorporates an open-drain active high comparator and internal reference providing a 0.6-V threshold. An external resistor divider sets the current trip point, and the comparator output will assert high when a voltage greater than 0.6 V is preset at the CMPin pin. Switch SW1 can be used to put the comparator in either latch or transparent mode. When in latch mode, SW1 can be moved to the reset position to clear the alert. The switch will then automatically return to the latch position. When the comparator threshold is reached, LED D1 will turn on.
