FM809 Rev. A.1
FM809
Precision Reset Generator Circuit
General Description
The FM809 features comprehensive reset generation for
microcontroller/microprocessor based systems. If the system V
CC
voltage level is determined to be in an out-of-tolerance state, the
device automatically generates a low-going reset signal. The
reset signal is held in the active state (low) for a specified duration
(minimum 140 ms) after the V
CC
returns to an in-tolerance state.
The FM809 is fabricated using CMOS technology. The FM809 is
available in the SOT-23 package.
