WS2833

Features and functions
● CMOS process, low power consumption.
● The control circuit uses fewer peripheral devices and is easy to use.
● The control circuit power supply voltage is DC2.0V~5.5V, the working voltage is wide, and it is suitable for most rechargeable batteries.
● Built-in triode, direct push current is more than 100mA, which can directly drive the LED light string.
● External 32.768KHz crystal oscillator, precise timing, the control circuit can realize the timed switch function, specifically 6 hours on, 18 hours off, and cycle in sequence.
● If you need to light up again after the timed shutdown, you need to power on again.
● TS quick test: TEST is grounded, and it flashes three times quickly and then stays on.

Main application areas
● LED Christmas light string, LED copper wire light string
● Other types of LED lamps

Product Overview
WS2833 is a low-power timing light string controller with built-in drive circuit and timing circuit, few external parts, and can realize the cyclic timing switch function through an external crystal oscillator. It is mainly used for LED Christmas light strings, decorative light strings, advertisements, etc. powered by three or four rechargeable batteries and single lithium battery. The IC has a built-in triode, and the direct-drive 1W LED current can reach more than 100mA. The default power-on is OFF; when the TIME pin is grounded, the LED works in a cyclic timing; when the T24 pin is grounded, the LED is always on; TS is the test pin. When TS is grounded, the LED flashes 3 times and then returns to the normal state.
