The LTC2901-1CGN from LT is a programmable quad supply monitor capable of simultaneously monitoring up to four supply voltages. It features 16 user-selectable combinations of voltage thresholds, including standard voltages like 5V, 3.3V, 2.5V, and 1.8V, as well as adjustable options. The device boasts a guaranteed threshold accuracy of ±1.5% over temperature, ensuring reliable operation.
This supply monitor includes adjustable reset and watchdog timer functions, allowing for customization of delay times using external capacitors. The LTC2901-1CGN variant features an open-drain RST output, suitable for various system configurations. It also provides individual non-delayed monitor outputs for each supply, enhancing system diagnostics. With a low supply current of only 43μA typical, it is ideal for power-conscious applications.
The LTC2901-1CGN is supplied in a 16-lead narrow SSOP package, designed for surface mounting. Its robust design includes power supply glitch immunity, ensuring stable reset operation without false triggering. The reset output is guaranteed to be in the correct state for VCC down to 1V.
