12 HYS2
Input of Comparator hysteresis (Hysteresis) to set. Logic
inputs, HYS1 and HYS2 set the comparator hysteresis .
13 GND Negative Terminal of Power Supply(Ground)
14 BLINK
Input of flash output control. Logic input, when the comparator
output is low, the comparator flip CHRG threshold control input
is low, and BLINK pin is high, the comparator output is about 500
ms conversion time at intervals , the duration of high and low the
same.
15 NC No Connection.
16 VDD
Positive Terminal of Power Supply. This pin is the power supply
to internal circuit.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other
conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect device reliability.
