TCM809  
TCM810  
3-Pin Microprocessor 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  
RESET Output Guaranteed to VCC = 1.0V (TCM809)  
Low 17µA Supply Current  
VCC Transient Immunity  
Small 3-Pin SOT-23B Package  
No External Components  
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.  
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 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 3-Pin SOT-23B  
package.  
TYPICAL APPLICATIONS  
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.
