TC1277-10ENBTR Description

Short technical summary and product information.

The Microchip Technology TC1277-10ENBTR is a cost-effective system supervisor circuit designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. It is optimized for 3.3V systems and features a precise VCC monitor with a 2.88V threshold.

 

The reset output is active high and is driven active within 20 µs of VCC falling through the reset voltage threshold. The RESET signal is maintained active for a minimum of 100 ms after VCC rises above the reset threshold. The output remains valid down to VCC = 1.8V, making it suitable for battery-powered equipment.

 

This device is available in a small 3-Pin SOT-23 package and requires no external components. Its design includes VCC transient immunity and is optimized to reject fast transient glitches on the VCC line. Applications include computers, embedded systems, and critical µP power supply monitoring.

 

Key electrical specifications include a 2.88V reset threshold and a minimum reset output duration of 100ms. The operating temperature range is -40°C to +85°C. The device is surface-mounted in a SOT-23-3 package.
