Reset Generator Circuit
4.5.2
EFFECT OF TEMPERATURE ON
The output signals from the voltage detect circuit and
the manual Reset with glitch filter circuit are OR’d
together and used to activate the Reset generator
module.
After the Reset conditions have been removed (the MR
pin is no longer forced low and the input voltage is
greater than the trip point voltage), the Reset generator
RESET POWER-UP TIMER (t RPU )
The Reset Delay Timer time-out period (t RST )
determines how long the device remains in the Reset
condition. This time out is affected by the device V DD
and the temperature. Typical responses for varying
V DD values and temperatures are presented in
circuit determines the Reset delay time-out required.
There are three options for the delay circuit. These are:

4.5.1 RESET DELAY TIMER
The Reset Delay Timer ensures that the TC127XA
device will “hold” the embedded system in Reset until
the system voltage has stabilized. The Reset Delay
The Reset Delay Timer starts when the voltage detect
circuit output AND the manual Reset with glitch filter
circuit output become inactive. While the Reset Delay
Timer is active, the RST or RST pin is driven to the
active state. When the Reset Delay Timer times out,
the RST or RST pin is driven inactive.

The Reset Delay Timer (t RST ) starts after the device
voltage rises above the “actual” trip point (V TRIP ).
When the Reset Delay Timer times out, the Reset out-
put pin (RST/RST) is driven inactive.
The Reset Delay Timer is cleared if either, or both, the
voltage detector circuit output and the manual Reset
with glitch filter circuit output become active. The RST
or RST pin continues to be driven to the active state.
(t RST ) is active or inactive.
