Pin Description
PIN
NAME
FUNCTION
1
RESET
Open-Drain, Active-Low Reset Output.
RESET
asserts when any input voltage falls below the selected
threshold, the watchdog timer expires, or when
MR
is pulled low.
RESET
remains asserted for default
(200ms) or adjustable reset timeout period after all assertion-causing conditions are cleared. An
external pullup resister is required.
2
SRT
Reset Timeout Adjust Input. Connect an external capacitor between SRT and GND to set the reset
timeout period. The timeout period is calculated by t
RP
= 4.348E6 x C
SRT
(t
RP
in seconds and C
SRT
in
Farads). To use the factory default period of 200ms connect SRT to V
CC
.
3
SWT
Watchdog Timeout Adjust Input. Connect an external capacitor between SWT and GND to set the
watchdog timeout period. The adjustable timeout period is calculated by t
WD
= 4.348E6 x C
SWT
(t
WD
in seconds and C
SWT
in Farads). Disable the watchdog timer by connecting SWT to GND. Connect
SWT to V
CC
to use the factory-default normal and initial periods of 1.6s and 102.4s, respectively.
