NTC open protection is implemented for  Direct drive SCR device safety. When NTC is open, it will cut off GATE  Auto Heating off after heating timer timeout output to disable heating, and the LED1 will flash at 1/8  Low cost 8-Pin DIP and SOIC package CLK. The device can be used in both 120V and 240V Applications power line supplier, automatically adjusting the heating  Hair Curler power according to the power line voltage to avoid heating appliance damage.

Heating-on: The device will be at heating-on state after heating-on button is pressed. Heating-off: This device enters heating-off state after its power-on reset or heating timer timeout or heating-off button pressed. Timer Once the device enters Heating-on state, internal timer start counting. It reaches timeout state and exit heating-on state after 216000 clock period, that is, the heating time is about 1 hour for 60Hz CLK signal, and 1.2 hour for 50Hz. Control signal output When working in Heating-on state, GATE/LED output will be related to NTC input and CLK input amplitude.
