Reset Timing
The power-on reset delay time is defined by the charging time of an external capacitor
C
d
which can be calculated as follows:
C
d
= (
t
d
×
I
d
)/
V
Definitions:
C
d
= delay capacitor
t
d
= delay time
I
d
= charge current, typical 5 mA
V
=
V
DU
, typical 1.9 V
V
DU
= upper delay switching threshold at
C
d
for reset delay time
The reset reaction time
t
rr
is the time it takes the voltage regulator to set the reset out
LOW after the output voltage has dropped below the reset threshold. It is typically 1
μ
s
for delay capacitor of 47 nF. For other values for
C
d
the reaction time can be estimated
using the following equation:
t
rr
≈
20 s/F
