TC1275/TC1276/TC1277 3-Pin Reset Monitors for 3.3V Systems Features • Precision VCC Monitor for 3.3V Systems • 100msec Minimum RESET, RESET Output Duration • Output Valid to VCC = 1.2V • VCC Transient Immunity • Small 3-Pin SOT-23B Package • No External Components General Description The TC1275/TC1276/TC1277 are cost-effective system supervisor circuits designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. No external components are required. The reset output is driven active within 20µsec of VCC falling through the reset voltage threshold. RESET is maintained active for a minimum of 100msec after VCC rises above the reset threshold. The TC1277 has an active-high RESET output while the TC1275 and TC1276 have an active-low RESET output.
