IN6
Input Voltage 6. Select undervoltage threshold using TH0–TH4. See Table 2.
For improved noise immunity, bypass IN6 to GND with a 0.1μF capacitor as
close to the device as possible.
Input Voltage 5. Select undervoltage threshold using TH0–TH4. See Table 2.
Power the device through IN2–IN5 or V
CC
(see the
Powering the
MAX6892/MAX6893/MAX6894
section). For improved noise immunity, bypass
IN5 to GND with a 0.1μF capacitor as close to the device as possible.
Input Voltage 4. Select undervoltage threshold using TH0–TH4. See Table 2.
Power the device through IN2–IN5 or V
CC
(see the
Powering the
MAX6892/MAX6893/MAX6894
section). For improved noise immunity, bypass
IN4 to GND with a 0.1μF capacitor as close to the device as possible.
Input Voltage 3. Select undervoltage threshold using TH0–TH4. See Table 2.
Power the device through IN2–IN5 or V
CC
(see the
Powering the
MAX6892/MAX6893/MAX6894
section). For improved noise immunity, bypass
IN3 to GND with a 0.1μF capacitor as close to the device as possible.
Input Voltage 2. Select undervoltage threshold using TH0–TH4. See Table 2.
Power the device through IN2–IN5 or V
CC
(see the
Powering the
MAX6892/MAX6893/MAX6894
section). For improved noise immunity, bypass
IN2 to GND with a 0.1μF capacitor as close to the device as possible.
Input Voltage 1. Select undervoltage threshold using TH0–TH4. See Table 2.
For improved noise immunity, bypass IN1 to GND with a 0.1μF capacitor as
close to the device as possible.
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 watchdog
timeout period, the watchdog output asserts low. The watchdog timeout period
is externally adjustable with capacitor C
SWT
or selectable for a fixed internal
timeout period. The watchdog has a long timeout period (92.16s minimum fixed
or 64x the adjusted short timeout period) after each reset event and a short
timeout period (1.44s minimum or an adjusted timeout period) after the first
valid WDI transition.
Open-Drain, Power-Good Output 1. PG1 asserts low when the voltage input at
IN1 is below the pin-selectable/adjustable input threshold or
ENABLE
is pulled
high. PG1 deasserts with a factory preset timeout period of 6.25ms.
