Obsolete Device

TC1272/TC1273/TC1274

3-Pin Reset Monitors for 5V Systems

Features

General Description

• Precision V_CCMonitor for 5.0V Systems

The TC1272/TC1273/TC1274 are cost-effective

system supervisor circuits designed to monitor V_CCin

digital systems and provide a reset signal to the host

processor when necessary. No external components

are required.

• 100 ms Minimum RESET, RESET Output

Duration

• Output Valid to V_CC= 1.2V

• V_CCTransient Immunity

• Small 3-Pin SOT-23 Package

• No External Components

The reset output is driven active within 20 µs of V_CC

falling through the reset voltage threshold. RESET is

maintained active for a minimum of 100 ms after V_CC

rises above the reset threshold. The TC1274 has an

active-high RESET output, while the TC1272 and

TC1273 have an active-low RESET output. The

TC1272 and TC1274 each have a complimentary out-

put, while the TC1273 has an open-drain output. The

output of the TC1272 and TC1273 is valid down to V_CC

= 1.2V. The TC1274 is valid down to V_CC= 1.8V. All

three devices are available in a 3-Pin SOT-23

package.

Applications

• Computers

• Embedded Systems

• Battery-Powered Equipment

• Critical µP Power Supply Monitoring

Package Type

3-Pin SOT-23

The TC1272/TC1273/TC1274 devices are optimized to

reject fast transient glitches on the V_CCline.
