Obsolete Device  
TC1275/TC1276/TC1277  
3-Pin Reset Monitors for 3.3V Systems  
Features  
General Description  
• Precision VCC Monitor for 3.3V Systems  
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.  
• 100 ms Minimum RESET, RESET Output  
Duration  
• Output Valid to VCC = 1.2V  
• VCC Transient Immunity  
• Small 3-Pin SOT-23 Package  
• No External Components  
The reset output is driven active within 20 µs of VCC  
falling through the reset voltage threshold. RESET is  
maintained active for a minimum of 100 ms 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. 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 VCC = 1.2V. The  
TC1277 is valid down to VCC = 1.8V. All three devices  
are available in a 3-Pin SOT-23 package.  
Applications  
• Computers  
• Embedded Systems  
• Battery Powered Equipment  
• Critical µP Power Supply Monitoring  
Device Selection Table  
The TC1275/TC1276/TC1277 devices are optimized to  
reject fast transient glitches on the VCC line.
