TC1270/TC1271  
4-Pin Reset Monitors  
Features:  
General Description  
• Precision VCC Monitor for 1.8V, 2.7V, 3.0V, 3.3V  
and 5.0V Nominal Supplies  
The TC1270 and TC1271 are cost-effective system  
supervisor circuits designed to monitor VCC in digital  
systems and provide a reset signal to the host  
processor when necessary. A manual reset input is  
provided to override the reset monitor, and is suitable  
for use as a push button reset. No external components  
are required.  
• Manual Reset Input  
• 140 ms Minimum RESET, Reset Output Duration  
• RESET Output Valid to VCC = 1.0V (TC1270)  
• Low 7 µA Supply Current  
• VCC Transient Immunity  
The reset output is driven active within 20 µs (4 µs for  
F version) of VCC falling through the reset voltage  
threshold. Reset is maintained active for a minimum of  
140 ms after VCC rises above the reset threshold. The  
TC1271 has an active-high RESET output while the  
TC1270 has an active-low RESET output. The output  
of the TC1270 is valid down to VCC = 1V. Both devices  
are available in a 4-Pin SOT-143 package.  
• Small 4-Pin SOT-143 Package  
• No External Components  
• Replacement for MAX811/812 and Offers a Lower  
Threshold Voltage Option  
Applications:  
• Computers  
The TC1270/TC1271 devices are optimized to reject  
fast transient glitches on the VCC line. Low supply  
current of 7 µA (VCC = 3.3V) makes these devices  
suitable for battery powered applications.  
• Embedded Systems  
• Battery Powered Equipment  
• Critical µP Power Supply Monitoring
