PRELIMINARY INFORMATION

TCM809

TCM810

3-PIN µP RESET MONITORS

FEATURES

GENERAL DESCRIPTION

■ Precision V_CCMonitor 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 V_CCin digital sys-

tems and provide a reset signal to the host processor when

necessary. No external components are required.

■

RESET Output Guaranteed to V_CC= 1.0V (TCM809)

The reset output is driven active within 20msec of V

■ Low 17µA Supply Current

■ V_CCTransient Immunity

■ Small SOT-23B-3 Package

■ No External Components

falling through the reset voltage threshold. Reset is main-

tained active for a minimum of 140msec after V_CCrises

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 V_CC= 1V. Both devices are available in a

SOT-23B-3 package.

The TCM809/810 are optimized to reject fast transient

glitches on the V_CCline. Low supply current of 17µA

(V_CC= 3.3V) makes these devices suitable for battery

powered applications.
