Typical Application Circuit

General Description

The TCM809 and TCM810 are cost-effective system

supervisor circuits designed to monitor VDD in digital

systems; providing a reset signal to the host processor,

when

necessary.

No

external

components

are

required.

The RESET output is typically driven active within

65 µsec of VDD falling through the reset voltage thresh-

old. RESET is maintained active for a minimum of

140 msec after VDD 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/TCM810 is valid down to

VDD = 1V. Both devices are available in 3-Pin SC-70

and SOT-23B packages.

The TCM809/TCM810 are optimized to reject fast

transient glitches on the VDD line. A low supply current

of 9 µA (typ., VDD = 3.3V) make these devices suitable

for battery-powered applications.
