Typical Application Circuit

General Description

The TCM809 and TCM810 are cost-effective system

supervisor circuits designed to monitor VDD in digital

systems and provide a reset signal to the host proces-

sor, 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 out-

put 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 is 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.
