Obsolete Device  
TC1278/TC1279  
3-Pin Reset Monitors for 5V Systems  
Features  
General Description  
• Precision VCC Monitor for 5.0V System Supplies  
• 250 ms Minimum RESET Output Duration  
• Output Valid to VCC = 1.2V  
The TC1278/TC1279 are cost-effective system super-  
visor 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  
open-drain output uses an internal pull-up resistor of  
approximately 6 kΩ.  
• VCC Transient Immunity  
• Small 3-Pin SOT-23 Package  
• No External Components  
The reset output is driven active within 5 µs of VCC  
falling through the reset voltage threshold. RESET is  
maintained active for a minimum of 250 ms after VCC  
rises above the reset threshold. The TC1278 has an  
active-high RESET output, while the TC1279 has an  
active-low RESET output, with both devices having an  
open-drain output stage. The output is valid down to  
VCC = 1.2V. Both devices are available in a 3-Pin  
SOT- 23 package.  
• Internal Pull-up Resistor  
• Available in 3 different voltage detection levels:  
- 4.625V (typ.), -5 suffix  
- 4.375V (typ.), -10 suffix  
- 4.125V (typ.), -15 suffix  
Applications
