WS2832B

Features and functions
● CMOS technology, 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.
● After the timed shutdown, if you need to light up again, you need to power on again.
● TS quick test: TEST is grounded, 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 timed light string controller with built-in drive circuit and timing circuit, few external parts, and can realize the cyclic timed switch function through an external crystal oscillator. Mainly used for LED Christmas light strings, decorative light strings, advertisements, etc. powered by three or four rechargeable batteries or single lithium battery. The IC has a built-in transistor, and the direct-drive current of 1W LED can reach more than 100mA. The default setting is OFF when powered on; when the TIME pin is grounded, the LED works in a cycle timing; when the T24 pin is grounded, the LED is always on; TS is the test pin, and when TS is grounded, the LED flashes 3 times and then returns to the normal state.
