Device Overview

Summary

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. The reset output is driven active within 20µsec (4µsec for F version) of VCC falling through the reset voltage threshold. RESET is maintained active for a minimum of 140msec after VCC rises above the reset threshold. The TC1271 has an active-high RESET output while the TC1270 has an active-low RESET output. The output of the TC1270 is valid down to VCC = 1V. Both devices are available in a 4-Pin SOT-143 package. The TC1270/1 are optimized to reject fast transient glitches on the VCC line. Low supply current of 7µA (VCC = 3.3V) makes these devices suitable for battery powered applications.
