IMP1832S Product details

Description

Pin Number 8-Pin Package 1 2 3 4 5 Name PBRST TD TOL GND RESET Function Debounced manual pushbutton reset input Watchdog time delay selection.(tTD = 150ms for TD = GND, tTD = 610ms for TD = Open, and tTD =1200ms for TD = VCC) Selects 10% (TOL connected to GND) or 20% (TOL connected to VCC) trip point tolerance Ground Active HIGH reset output.RESET is active: 1. If VCC falls below the reset voltage trip point.2. If PBRST is LOW.3. If ST is not strobed LOW before the timeout period set by T
