Pin Description (continued)
PIN
NAME
FUNCTION
4
GND
Ground
5
WDI
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 timeout period, RESET asserts. WDI is
internally pulled down to GND through a 10A current sink.
6
MR
Active-Low Manual Reset Input. Pull MR low to assert RESET. RESET will remain asserted for its
preset/adjustable reset timeout period when MR is driven high. Leave MR unconnected or connect to
DBP if unused. MR is internally pulled up to DBP through a 10A current source.
7
MARGIN
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 DBP through a 10A current source. MARGIN overrides MR if both are asserted
at the same time.
8
TH4
Threshold Selection Input 4. Logic input to select desired threshold. Connect TH4 to GND or DBP.
See Table 2 for available thresholds. Input has no internal pullup or pulldown.
9
TH3
Threshold Selection Input 3. Logic input to select desired threshold. Connect TH3 to GND or DBP.
See Table 2 for available thresholds. Input has no internal pullup or pulldown.
10
TH2
Threshold Selection Input 2. Logic input to select desired threshold. Connect TH2 to GND or DBP.
See Table 2 for available thresholds. Input has no internal pullup or pulldown.
11
TH1
Threshold Selection Input 1. Logic input to select desired threshold. Connect TH1 to GND or DBP.
See Table 2 for available thresholds. Input has no internal pullup or pulldown.
12
TH0
Threshold Selection Input 0. Logic input to select desired threshold. Connect TH0 to GND or DBP.
See Table 2 for available thresholds. Input has no internal pullup or pulldown.
13
VCC
Internal Power-Supply Voltage. Bypass VCC to GND with a 1F ceramic capacitor as close to the
device as possible. VCC supplies power to the internal circuitry. VCC is internally powered from the
highest of the monitored IN1–IN4 voltages. Do not use VCC to supply power to external circuitry. To
externally supply VCC, see the Powering the MAX6886 section.
14
DBP
Digital Bypass Voltage. The internally generated voltage at DBP supplies power to internal logic and
output RESET. Connect a 1F capacitor from DBP to GND as close to the device as possible. Do not
use DBP to supply power to external circuitry.
15
IN6
Input Voltage Detector 6. Select the undervoltage threshold using TH0–TH4. See Table 2. IN6 cannot
supply power to the device. For improved noise immunity, bypass IN6 to GND with a 0.1F capacitor
installed as close to the device as possible.
16
IN5
Input Voltage Detector 5. Select the undervoltage threshold using TH0–TH4. See Table 2. IN5 cannot
supply power to the device. For improved noise immunity, bypass IN5 to GND with a 0.1F capacitor
installed as close to the device as possible.
17
IN4
Input Voltage Detector 4. Select the undervoltage threshold using TH0–TH4. See Table 2. For
improved noise immunity, bypass IN4 to GND with a 0.1F capacitor installed as close to the device
as possible. Power the device through IN1–IN4 or VCC (see the Powering the MAX6886 section).
18
IN3
Input Voltage Detector 3. Select the undervoltage threshold using TH0–TH4. See Table 2. For
improved noise immunity, bypass IN3 to GND with a 0.1F capacitor installed as close to the device
as possible. Power the device through IN1–IN4 or VCC (see the Powering the MAX6886 section).
19
IN2
Input Voltage Detector 2. Select the undervoltage threshold using TH0–TH4. See Table 2. For
improved noise immunity, bypass IN2 to GND with a 0.1F capacitor installed as close to the device
as possible. Power the device through IN1–IN4 or VCC (see the Powering the MAX6886 section).
20
IN1
Input Voltage Detector 1. Select the undervoltage threshold using TH0–TH4. See Table 2. For
improved noise immunity, bypass IN1 to GND with a 0.1F capacitor installed as close to the device
as possible. Power the device through IN1–IN4 or VCC (see the Powering the MAX6886 section).

EP
Exposed Paddle. Internally connected to GND. Connect EP to GND or leave floating.
