Description:: voltage supervisor (reset IC) with programmable window watchdog

ECAD Model:

Datasheet:: tps3813

Overview

Description
This application note describes a circuit that can be used to selectively disable the watchdog timer in TI's family of supervisors. The watchdog timer in many of these devices can be disabled by leaving the WDI pin open. In this mode, an internal signal is provided to periodically reset the watchdog time-out timer. If the WDI pin is grounded or pulled high, the internal trigger is disabled and watchdog time-outs occur.

Features
Extends the watchdog timer time-out period as long as the boot time requires
Ideal for applications with long boot times but require a watchdog with a short time-out period
Shorter watchdog time-out periods are generally preferred in applications that need to respond quickly to processor fault conditions

Applications
Microprocessor applications where a watchdog supervisor is required
Applications with long boot times
Applications that require a watchdog with a short time-out period
