FM810 Rev. A.1
General Description
The FM810 features a highly accurate voltage reference against
which the VCC is compared. Once the VCC is below the specified
threshold, it will drive the RESET line and continue to hold it high
till the V
CC returns above the threshold and the time for the RESET
pulse duration has expired. The FM810 is immune to short
negative going transients on the V
CC line. The placement of a
0.1
F bypass capacitor as close as possible to the V
CC pin
provides additional transient immunity.
For a V
CC value below 1.0V-1.3V, the FM810 does not sink current
on the RESET pin.
This is not a problem in most systems since most common devices
are not functional in this range. If it is desired for the FM810 reset
to be functional below the range above, it is suggested to use a
100K
pull-down resistor between RESET and V
SS.
Interfacing to Bidirectional reset pins
FM810 can be used with microprocessors with bidirectional reset
pins. In order to allow the microprocessor to drive the reset line, the
output of the FM810 must be connected to the microprocessor
through a 4.7k
resistor. This will ensure that the RESET line has
correct level at both the FM810 as well as the device end.
