TC1278/TC1279

3-Pin Reset Monitors for 5V Systems

Features

•

Precision V

Monitor for 5.0V System Supplies

250msec Minimum RESET Output Duration

Output Valid to V

= 1.2V

Transient Immunity

Small 3-Pin SOT-23B Package

No External Components

General Description

The TC1278/TC1279 are cost-effective system super-

visor circuits designed to monitor V

in digital systems

and provide a reset signal to the host processor when

necessary. No external components are required.

The reset output is driven active within 5µsec of V

falling through the reset voltage threshold. RESET is

maintained active for a minimum of 250msec after V

rises above the reset threshold. The TC1278 has an

active-high RESET output while the TC1279 has an

active-low RESET output, and both devices have an

open drain output stage. The output is valid down to

= 1.2V. Both devices are available in a 3-Pin SOT-

23B package.
