Description

Shape about 12mm * 12mm, operating voltage 2v-5v, timing can be set to a minimum to a maximum of 2 seconds 1,000 hours, as indicated below description

Function and Design

1. The circuit according to claim connected and set a good time resistance and supply voltage;

2. Before the power not trigger output is high;

3. Trigger terminal “falling” trigger effective immediately after the trigger output terminal goes low at the same time start the timer circuit;

4. Set the timer time to recover after the output terminal is high, wait for the next “falling” trigger;

5. The chip is not repeated triggered, meaning that continue to trigger in the period after the trigger chip output low if the trigger is invalid;

6. The trigger end of “falling” Trigger refers to the instantaneous change from high level to a low level;

7. General refers to VCC high voltage, low means 0-0.3v or GND,

provided that they meet the level requirements can be;

8. trigger terminal can be connected to touch switch or microcontroller IO port or other digital circuits have a “falling” can effectively trigger;

9. The trigger can be designed to power, only to trigger a short circuit to ground, power is triggered, the time to recover after the output to a high level, waiting for the next Falling edge trigger again.

Chip Features: 

1. The use of low-power CMOS technology, lead-free and environmentally friendly.

2. Direct Push can output low LED

(please add current limiting resistor), the output high may push transistor (please add current limiting resistor).

3. Available resistance adjusting timing, there are 8 * N (N = 0.1.2.3) times the timing selection,

time can be adjusted from 2s-1000h.

4. Optional trigger timing and triggering termination ground electric timer.

5. standby output high, falling edge trigger, post-trigger output low, after the delay recovery high.

The pot is marked with 1 to 10 hours and this will be ideal for most applications. The tactile button starts the timing and the buzzer sounds when the time is up. Two output pins are also provided on the PC board to connect to other devices to turn them ON.
The output of the board turns ON a device such as a relay, after say 5 hours, and the contacts on the relay will turn the device OFF. The buzzer on the board will let you know the 5 hours is up. 

The project is connected to 3 x AA cells (4.5v) (in a battery box)
Consumption when timing: 100uA
Output: pull-up  3mA    pull-down 30mA
Connecting the pads at P1   and also the pads at P2 increases the delay by 8 times, making the timing up to 80 hours. (but don’t let P1 pads touch P2 pads). Changing the pot to 20M creates 1,000 hours.

P1 short circuit (two small pad short circuit) timing time is equal to the time in the resistance meter multiplied by 8 times

P2 short circuit (two small pad short circuit) timing time is equal to the time in the resistance meter multiplied by 64 times

P1, P2 short circuit at the same time (two small pad short circuit) timing time is equal to the time in the resistance meter multiplied by 512 times
