TH1
Threshold Selection Input 1. Logic input to select desired thresholds. Connect
TH1 to GND or DBP. See Table 2 for available thresholds. Input has no internal
pullup or pulldown.
Threshold Selection Input 2. Logic input to select desired thresholds. Connect
TH2 to GND or DBP. See Table 2 for available thresholds. Input has no internal
pullup or pulldown.
Threshold Selection Input 3. Logic input to select desired thresholds. Connect
TH3 to GND or DBP. See Table 2 for available thresholds. Input has no internal
pullup or pulldown.
Threshold Selection Input 4. Logic input to select desired thresholds. Connect
TH4 to GND or DBP. See Table 2 for available thresholds. Input has no internal
pullup or pulldown.
Watchdog Timeout Adjust Input. Connect SWT to V
CC
to select the default
watchdog timeout period. Connect an external capacitor between SWT and
GND to adjust the watchdog timeout period. The adjustable timeout period is
calculated by t
WP
= 4.348E6 x C
SWT
(t
WP
in seconds and C
SWT
in Farads).
Disable the watchdog timer by connecting SWT to GND.
Reset Timeout Adjust Input. Connect SRT to V
CC
to select the default reset
timeout period. Connect an external capacitor between SRT and GND to adjust
the reset timeout period. The adjustable timeout period is calculated by t
RP
=
4.348E6 x C
SWT
(t
RP
in seconds and C
SRT
in Farads).
Active-Low, PG_ Enable Input. Pull
ENABLE
high to force all PG_ outputs low.
PG_ outputs remain asserted for their timeout period when
ENABLE
is
driven/pulled low.
ENABLE
is internally pulled down to GND through a 10μA
current sink.
Internal Supply Voltage. Bypass V
CC
to GND with a 1μF capacitor as close to
the device as possible. V
CC
supplies power to the internal circuitry. V
CC
is
internally powered from the highest of the monitored IN2–IN5 voltages. Do not
use V
CC
to supply power to external circuitry. To externally supply V
CC,
see the
Powering the MAX6892/MAX6893/MAX6894
section
)
.
Digital Bypass Voltage. DBP supplies power to the output stages. Bypass DBP
to GND with a 1μF capacitor as close to the device as possible. Do not use
DBP to supply power to external circuitry.
Input Voltage 8. Select undervoltage threshold using TH0–TH4. See Table 2.
For improved noise immunity, bypass IN8 to GND with a 0.1μF capacitor as
close to the device as possible.
Input Voltage 7. Select undervoltage threshold using TH0–TH4. See Table 2.
For improved noise immunity, bypass IN7 to GND with a 0.1μF capacitor as
close to the device as possible.
