TCM810  
3-PIN µP RESET MONITORS  
FEATURES  
GENERAL DESCRIPTION  
Precision VCC Monitor for 3.0V, 3.3V, 5.0V  
Nominal System V Supplies  
140msec Guaranteed Minimum RESET, RESET  
Output Duration  
The TCM809 and TCM810 are cost-effective system  
supervisor circuits designed to monitor VCC in digital sys-  
tems and provide a reset signal to the host processor when  
necessary. No external components are required.  
RESET Output Guaranteed to VCC = 1.0V (TCM809)  
The reset output is driven active within 20msec of V

No External Components  
falling through the reset voltage threshold. Reset is main-  
tained active for a minimum of 140msec after VCC rises  
above the reset threshold. The TCM810 has an active-high  
reset output while the TCM809 has an active-low reset  
output. The output of the TCM809 is guaranteed valid down  
to VCC = 1V. Both devices are available in a  
SOT-23B-3 package.  
The TCM809/810 are optimized to reject fast transient  
glitches on the VCC line. Low supply current of 17µA  
(VCC = 3.3V) makes these devices suitable for battery  
powered applications.
