IMP Inc IMP1832S
The IMP1832 microprocessor supervisor can halt and restart a “hungup” or “stalled” microprocessor, restart a microprocessor after a power failure, and debounce a manual push-button microprocessor reset switch. The IMP1832 features over 40% lower supply current than the pin compatible Dallas Semiconductor DS1832. When VCC rises above the threshold voltage, the reset signals remain active for an additional 250ms minimum, allowing the power supply and system microprocessor to stabilize.IMP1832S Specifications

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”.
