Heating on The device will be of heating on state after heating-on button is on Heating off This device enter heating-off state after its power-on reset or heating timer timeout, and all pins will be the same status as after power-on reset. NTC open protection When NTC is open, NTC1 pin will be pulled low in the period of NTC open detected. Timer Once IC enters Heating-on State, internal timer starts to count. When time is out after 216000 clock period, it will exit heating-on state. That is, in case of 60Hz CLK signal, the heating time is about 1 hour; and 1.2 hour for 50Hz. In heating-on state, temperature is regulated to the selected temperature by the IC through NTC close control loop. Control signal output When working in Heating-on state, Gate/LED output will be related to NTC1 input and CLK input amplitude.
