LED Control IC

W2RG012RN

Optimal IC for LED Control

• An exponential function-based PWM gradation control for up to

256 gradations, enabling beautiful fade-in and fade-out.

• Dynamic drive of LEDs connected in a matrix form; individual

control of up to 128 LED Lines.

• Serial bus connection permitting connection of up to 15 ICs on

the same communication line.

• 24 constant current outputs contained in a small package of

7x7mm.

• Built-in thermal shutdown.

• RoHS Compliant

Absolute Maximum Ratings

Note: 1. Take the power consumption and allowable power dissipation rating into consideration.

2. Values when the product is mounted on a standard substrate (70 mm x 70 mm x1.6 mmt, FR-4).

When using the product at Ta = 25°C or higher, the values must be decreased using the constant of temperature decrease R
