NAME
FUNCTION
11
RESET
Reset Output. Configurable, active-low, open drain, or weak pullup. RESET assumes its
programmed conditional output state when VCC exceeds UVLO (2.5V).
22
WDO
Watchdog Timer Output. Configurable, active-low, open drain, or weak pullup. WDO
asserts when WDI is not toggled with a valid high-to-low or low-to-high transition within
the watchdog timeout period.
33
UV/OV
Undervoltage/Overvoltage Output. Configurable, active-low, open drain, or weak pullup.
(2.5V).
44
GND
Ground
55
WDI
Watchdog Timer Input. Logic input for the watchdog timer function. If WDI is not toggled
with a valid low-to-high or high-to-low transition within the watchdog timeout period,
WDO asserts. Progam initial and normal watchdog timeout periods from 6.25ms to
102.4s. WDI is internally pulled down to GND through a 10A current sink.
66
MR
Manual Reset Input. Program MR to assert RESET and/or UV/OV when MR is asserted.
Leave MR unconnected or connect to DBP if unused. MR is internally pulled up to DBP
through a 10A current source.
Typical Operating Characteristics (continued)
(VIN1–VIN4 or VCC = 5V, AUXIN = WDI = GND, MARGIN = MR = DBP. Typical values are at TA = +25°C, unless otherwise noted.)
