TC1275/TC1276/TC1277 Reset Monitors
●General Description
▲The TC1275/TC1276/TC1277 are cost-effective system supervisor circuits designed to monitor V-CC 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 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 TC1277 has an active-high RESET output while the TC1275 and TC1276 have an active-low RESET output. TC1275 and TC1277 each have a complimentary output while the TC1276 has an open drain output. The output of the TC1275 and TC1276 is valid down to V-CC = 1.2V. The TC1277 is valid down to V-CC = 1.8V. All three devices are available in a 3-Pin SOT-23 package.
▲The TC1275/TC1276/TC1277 devices are optimized to reject fast transient glitches on the V-CC line
