General Description

The TC1270 and TC1271 are cost-effective system supervisor circuits designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. A manual reset input is provided to override the reset monitor, and is suitable for use as a push button reset. No external components are required.

Features:

• Precision VCCMonitor for 1.8V, 2.7V, 3.0V, 3.3V and 5.0V Nominal Supplies

• Manual Reset Input

• 140 ms Minimum RESET, Reset Output Duration

• RESETOutput Valid to VCC= 1.0V (TC1270)

• Low 7 µA Supply Current

• VCC Transient Immunity

• Small 4-Pin SOT-143 Package

• No External Components

• Replacement for MAX811/812 and Offers a Lower

Threshold Voltage Option

Applications:

• Computers

• Embedded Systems

• Battery Powered Equipment

• Critical µP Power Supply Monitoring
