Manual Reset Input. Pull MR low to assert RESET. Connect MR to WDO to generate resets
when the watchdog timer expires. Leave MR unconnected or connect to DBP if unused. MR is
internally pulled up to BP through a 10µA current source.
Margin Input. When MARGIN is pulled low, RESET is held in its existing state independent of
subsequent changes in monitored input voltages or the watchdog timer expiration. MARGIN is
internally pulled up to BP through a 10µA current source. Leave MARGIN unconnected or
connect to BP if unused. MARGIN overrides MR if both are asserted at the same time.
Watchdog Timer Input. Logic input for the watchdog timer function. If WDI is not strobed with a
valid low-to-high or high-to-low transition within the selected watchdog timeout period, WDO
asserts. WDI is internally pulled down to GND through a 10µA current sink.
Internal Connection. Leave unconnected.
Internal Power-Supply Voltage. Bypass V
the device as possible. V
from the highest of the monitored IN1–IN4 voltages. Do not use V
circuitry. To externally supply V
Bypass Voltage. The internally generated voltage at BP supplies power to internal logic and
output RESET. Connect a 1µF capacitor from BP to GND as close to the device as possible. Do
not use BP to supply power to external circuitry.
Input Voltage Detector 6. IN6 monitors both undervoltage and overvoltage conditions. See the
thresholds options (Tables 1 and 2) for available thresholds. IN6 cannot power the device. For
improved noise immunity, bypass IN6 to GND with a 0.1µF capacitor installed as close to the
device as possible.
Input Voltage Detector 5. IN5 monitors both undervoltage and overvoltage conditions. See the
thresholds options (Tables 1 and 2) for available thresholds. IN5 cannot power the device. For
improved noise immunity, bypass IN5 to GND with a 0.1µF capacitor installed as close to the
device as possible.
Input Voltage Detector 4. IN4 monitors both undervoltage and overvoltage conditions. See the
thresholds options (Tables 1 and 2) for available thresholds. Power the device through IN1–IN4
or V
bypass IN4 to GND with a 0.1µF capacitor installed as close to the device as possible.
Input Voltage Detector 3. IN3 monitors both undervoltage and overvoltage conditions. See the
thresholds options (Tables 1 and 2) for available thresholds. Power the device through IN1–IN4
or V
bypass IN3 to GND with a 0.1µF capacitor installed as close to the device as possible.
Input Voltage Detector 2. IN2 monitors both undervoltage and overvoltage conditions. See the
thresholds options (Tables 1 and 2) for available thresholds. Power the device through IN1–IN4
or V
bypass IN2 to GND with a 0.1µF capacitor installed as close to the device as possible.
Input Voltage Detector 1. IN1 monitors both undervoltage and overvoltage conditions. See the
thresholds options (Tables 1 and 2) for available thresholds. Power the device through IN1–IN4
or V
bypass IN1 to GND with a 0.1µF capacitor installed as close to the device as possible.
No Connection. Not internally connected.
