TCM809SENB713

监控电路 Microprocessor 2.93V

General Description TCM809SENB713

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 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 threshold.

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 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.
