3-Pin Reset Monitors For 5V Systems  
FEATURES  
GENERAL DESCRIPTION  
Precision VCC Monitor for 5.0V Systems  
100 msec Guaranteed Minimum RESET,  
RESET Output Duration  
The TC1272, TC1273 and 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.  
The reset output is driven active within 20µsec of VCC  
falling through the reset voltage threshold. Reset is main-  
tained active for a minimum of 100msec 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  
haveacomplimentary outputwhiletheTC1273hasanopen  
drain output. The output of the TC1272 and TC1273 is  
guaranteed valid down to VCC = 1.2V. The TC1274 is  
guaranteed valid down to VCC =1.8 V. All three devices are  
available in a 3-Pin SOT-23B package.  
Output Guaranteed to VCC = 1.2V

TYPICAL APPLICATIONS  
Computers  
Embedded Systems  
Battery Powered Equipment  
Critical µP Power Supply Monitoring  
The TC1272/3/4 are optimized to reject fast transient  
glitches on the VCC line.
