TC1278/TC1279  
3-Pin Reset Monitors for 5V Systems  
Features  
General Description  
• Precision VCC Monitor for 5.0V System Supplies  
• 250msec Minimum RESET Output Duration  
The TC1278/TC1279 are cost-effective system super-  
visor circuits designed to monitor V in digital systems  
CC  
and provide a reset signal to the host processor when  
necessary. No external components are required.  
• Output Valid to V = 1.2V

• Small 3-Pin SOT-23B Package  
• No External Components  
falling through the reset voltage threshold. RESET is  
maintained active for a minimum of 250msec after V  
CC  
rises above the reset threshold. The TC1278 has an  
active-high RESET output while the TC1279 has an  
active-low RESET output, and both devices have an  
open drain output stage. The output is valid down to
