Description
1 IN1
The first negative input way of comparator. It can be monitored
directly connected or through an external resistor voltage divider
network to set the flip threshold voltage.
2 OUT1
The first way output of comparator. Open-drain output. When
IN1 rise, and exceed the comparator threshold, the device from
OUT1 to GND NMOSFET on, OUT1 output low. When IN1
drops and less than the comparator threshold, the device from
OUT1 to GND NMOSFET off, OUT1 output impedance
.
3 IN2
The second negative input way of comparator. It can be
monitored directly connected or through an external resistor
voltage divider network to set the flip threshold voltage .
4 OUT2
The second way output of comparator. Open-drain output.
When IN2 rise, and exceed the comparator threshold, the device
from OUT2 to GND NMOSFET on, OUT2 output low. When IN2
drops and less than the comparator threshold, the device from
OUT2 to GND NMOSFET off, OUT2 output impedance.
5 IN3
The third negative input way of comparator. It Can be
monitored directly connected or through an external resistor
voltage divider network to set the flip threshold voltage .
6 OUT3
The third way output of comparator.
Open-drain output. When
IN3 rise, and exceed the comparator threshold, the device from
OUT3 to GND NMOSFET on, OUT3 output low. When IN3
drops and less than the comparator threshold, the device from
OUT3 to GND NMOSFET off, OUT3 output impedance.
7 IN4
The forth negative input way of comparator. It Can be
monitored directly connected or through an external resistor
voltage divider network to set the flip threshold voltage .
8 OUT4
The forth way output of comparator.
Open-drain output. When
IN3 rise, and exceed the comparator threshold, the device from
OUT4 to GND NMOSFET on, OUT4 output low. When IN4
drops and less than the comparator threshold, the device from
OUT4 to GND NMOSFET off, OUT4 output impedance.
9 CHRG
Input of the comparator flip threshold control. When this pin
is high, the comparator flip threshold is 1.22V typically
(comparator input voltage drop); When this pin is low, the
comparator flip threshold is 1.256V typically (comparator input
voltage drop).
10 NC No Connection.
11 HYS1
Input of Comparator hysteresis (Hysteresis) to set. Logic
inputs, HYS1 and HYS2 set the comparator hysteresis .
