3-Pin Reset Monitors for 3.3V Systems

Features

General Description

• Precision V Monitor for 3.3V Systems

The TC1275/TC1276/TC1277 are cost-effective

system supervisor circuits designed to monitor V in

digital systems and provide a reset signal to the host

processor when necessary. No external components

are required.

• Output Valid to V = 1.2V

• V Transient Immunity

The reset output is driven active within 20µsec of V

• Small 3-Pin SOT-23B Package

falling through the reset voltage threshold. RESET is

maintained active for a minimum of 100msec after V

rises above the reset threshold. The TC1277 has an

active-high RESET output while the TC1275 and

TC1276 have an active-low RESET output. TC1275

and TC1277 each have a complimentary output while

the TC1276 has an open drain output. The output of the

TC1275 and TC1276 is valid down to V = 1.2V. The

TC1277 is valid down to V = 1.8V. All three devices

are available in a 3-Pin SOT-23B package.

Device Selection Table

The TC1275/TC1276/TC1277 devices are optimized to

reject fast transient glitches on the V line.
