First, the function description: ECH1062-242C
CMOS process technology, low power consumption. It adopts high voltage process, wide working voltage range and strong anti-interference ability. Working voltage is 2.4V-6.8V. Can use 6V battery directly.
The settable time is:
8 hours ON~ 16 hours OFF (H8 to VSS)
6 hours ON~ 18 hours OFF (H6 to VSS)
5 hours ON~ 19 hours OFF (H5 to VSS)
4 hours ON~ 20 hours OFF (H4 to VSS)
No time to work all the time (H24 to VSS)
Dedicated timing IC for 24-hour cycle operation.
Two outputs, LED1 is a soft mode candle flash, LED2 is working constantly.
The timed candle light uses a single-row 3-speed switch, and two timing states can be performed at the same time. When the switch is placed in the first gear of the selected second gear timing, it is powered on; if the switch is turned OFF, the power-on does not work. During the work, the switch can change the working state: work and not working.
(In the case of power-on, when timing change terminal is changed, re-time)
KEY is the ON/OFF button to control the opening and closing of the IC
The test method is tested with 1 hour flash, and the frequency is about 2Hz.
TIME grounding is a quick test, disconnection is normal mode
(When testing: I always light the I0 port, the candle flashes the IO port, the quick test mode is the same)
