FEATURES
x Pin compatible with the Dallas Semiconductor DS1832 — Over 40% lower supply current x 3.3V supply monitor x Push-pull output x Selectable watchdog period x Debounce manual push-button reset input x Precision temperature-compensated voltage reference and comparator x Power-up, power-down and brownout detection x 250ms minimum reset time x Active LOW and HIGH reset signal x Selectable trip point tolerance: 10% or 20% x Low-cost 8-pin DIP/SO and 8-pin MicroSO packages x Wide operating temperature – 40°C to +85°C – Selectable Trip -Point Tolerance and Watchdog Period – Push-Button Reset – Push-Pull Reset Outputs Precision temperature compensated reference and comparator circuits monitor the 3.3V, VCC input voltage. During power-up or when the VCC power supply falls outside selectable tolerance limits, both RESET and RESET become active. The trip point Also included is a watchdog timer to stop and restart a tolerance signal, TOL, selects the trip level tolerance to be either 10- or microprocessor that is “hung-up”.
