Obsolete Device  
TC1272/TC1273/TC1274  
3-Pin Reset Monitors for 5V Systems  
Features  
General Description  
• Precision VCC Monitor for 5.0V Systems  
The TC1272/TC1273/TC1274 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 TC1274 has an  
active-high RESET output, while the TC1272 and  
TC1273 have an active-low RESET output. The  
TC1272 and TC1274 each have a complimentary out-  
put, while the TC1273 has an open-drain output. The  
output of the TC1272 and TC1273 is valid down to VCC  
= 1.2V. The TC1274 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  
Package Type  
3-Pin SOT-23  
The TC1272/TC1273/TC1274 devices are optimized to  
reject fast transient glitches on the VCC line.
