MOD-TMD1-Q44 Multi-Function Delay Trigger Timing Chip Module, 2s – 1000h.
Specification:
Dimensions: 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.
Function and Design
- The circuit according to claim connected and set a good time resistance and supply voltage;
- Before the power does not trigger, output is high;
- Trigger terminal "falling", trigger effective immediately after the trigger output terminal goes low at the same time the timer circuit starts;
- Set the timer time to recover after the output terminal is high, wait for the next "falling" trigger;
- The chip is not repeat triggered, meaning that it continues to trigger in the period after the trigger chip output is low, if the trigger is invalid;
- The end of "falling" Trigger refers to the instantaneous change from high level to a low level;
- General refers to VCC high voltage, low means 0-0.3v or GND, provided that they meet the level requirements;
- Trigger terminal can be connected to touch switch or microcontroller IO port or other digital circuits which have a "falling" can effectively trigger;
- 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 Feature:
- The use of low-power CMOS technology, lead-free and environmentally friendly.
- Direct Push can output low LED (please add current limiting resistor), the output high may push transistor (please add current limiting resistor).
- Available resistance adjusting timing, there are 8 * N (N = 0.1.2.3) times the timing selection, time can be adjusted from 2s-1000h.
- Optional trigger timing and triggering termination ground electric timer.
- Standby output high, falling edge trigger, post-trigger output low, after the delay recovery high.
