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.
UV/OV assumes its programmed conditional output state when VCC exceeds UVLO
(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.)
