NAME FUNCTION

1 1 IN5 Monitored Input Voltage 5. See Table 1 for the input voltage threshold.

2 2 IN6 Monitored Input Voltage 6. See Table 1 for the input voltage threshold.

3 3 IN7 Monitored Input Voltage 7. See Table 1 for the input voltage threshold.

4 4 IN8 Monitored Input Voltage 8. See Table 1 for the input voltage threshold.

5 5 WDI

Watchdog Timer Input. If WDI remains low or high for longer than the watchdog timeout period,

RESET is asserted and the timer is cleared. The timer also clears whenever a reset is asserted or a

rising or falling edge on WDI is detected. The watchdog timer enters a startup period that allows 54s

for the first transition to occur before a reset. Leave WDI unconnected to disable the watchdog timer.

The WDI open-state detector uses a small 400nA current. Therefore, do not connect WDI to anything

that will source or sink more than 200nA. Note that the leakage current specification for most three-

state drivers exceeds 200nA.

Unmonitored Power-Supply Input

8 — OUT5

Output 5. When the voltage at IN5 falls below its threshold, OUT5 goes low and stays low until the

voltage at IN5 exceeds its threshold. The open-drain output has a 30µA internal pullup to V

9 — OUT6

Output 6. When the voltage at IN6 falls below its threshold, OUT6 goes low and stays low until the

voltage at IN6 exceeds its threshold. The open-drain output has a 30µA internal pullup to V

10 — OUT7

Output 7. When the voltage at IN7 falls below its threshold, OUT7 goes low and stays low until the

voltage at IN7 exceeds its threshold. The open-drain output has a 30µA internal pullup to V

11 — OUT8

Output 8. When the voltage at IN8 falls below its threshold, OUT8 goes low and stays low until the

voltage at IN8 exceeds its threshold. The open-drain output has a 30µA internal pullup to V

12 10 MR

Active-Low Manual Reset Input. Pull MR low to assert RESET low. RESET remains low for the reset

timeout period after MR is deasserted. MR is pulled up to V

through a 20kΩ resistor.

13 11 SRT

Set Reset Timeout Input. Connect a capacitor from SRT to GND to set the reset timeout period. The

reset timeout period can be calculated as follows:

Reset Timeout (s) = 2.06 x 10

(Ω) x C

SRT

(F). For the internal timeout period of 140ms (min), connect

SRT to V

NAME FUNCTION

14 12 MARGIN

Margin Disable Input. Pull MARGIN low to deassert all outputs (go into high state), regardless of the

voltage at any monitored input.

15 — OUT4

Output 4. When the voltage at IN4 falls below its threshold, OUT4 goes low and stays low until the

voltage at IN4 exceeds its threshold. The open-drain output has a 30µA internal pullup to V

16 — OUT3

Output 3. When the voltage at IN3 falls below its threshold, OUT3 goes low and stays low until the

voltage at IN3 exceeds its threshold. The open-drain output has a 30µA internal pullup to V

17 — OUT2

Output 2. When the voltage at IN2 falls below its threshold, OUT2 goes low and stays low until the

voltage at IN2 exceeds its threshold. The open-drain output has a 30µA internal pullup to V

18 — OUT1

Output 1. When the voltage at IN1 falls below its threshold, OUT1 goes low and stays low until the

voltage at IN1 exceeds its threshold. The open-drain output has a 30µA internal pullup to V

19 15 RESET

Active-Low Reset Output. RESET asserts low when any of the monitored voltages falls below its

respective threshold or MR is asserted. RESET remains asserted for the reset timeout period after all

monitored voltages exceed their respective thresholds and MR is deasserted. This open-drain output

has a 30µA internal pullup.

20 16 IN1 Monitored Input Voltage 1. See Table 1 for the input voltage threshold.

21 17 IN2 Monitored Input Voltage 2. See Table 1 for the input voltage threshold.

22 18 IN3 Monitored Input Voltage 3. See Table 1 for the input voltage threshold.

23 19 IN4 Monitored Input Voltage 4. See Table 1 for the input voltage threshold.

24 20 TOL

Threshold Tolerance Input. Connect TOL to GND to select 5% threshold tolerance. Connect TOL to

to select 10% threshold tolerance.
