Mingjiada supplies the new original MBI5253GFN-A 16-channel PWM constant current LED driver designed for LED video applications, using internal pulse width modulation (PWM) control with 14-bit/13-bit colour depth selection.


The MB5253 features a 16-bit shift register that converts serial input data into a gray level per pixel for the output port. 16 regulated current ports are designed to provide a uniform and constant current sink for driving LEDs with a wide range of VF variations.


Features

3V to 5.5V supply voltage

16 constant current output channels

Constant output current range:

-0.5~20mA@5V power supply voltage

-0.5~15mA@3.3V power supply voltage

Excellent output current accuracy:

Between channels: <±2.5% (max)

Between ICs: <±3% (max)

Digital power-on reset

Built-in 16K-bit SRAM, supports time multiplexing of 1~32 scans

14-bit/13-bit colour depth PWM control for improved visual refresh rate

6-bit current gain, 12.5% to 100%

LED fault isolation

-Crossover elimination due to LED faults

Forced LED open circuit detection

Integrated ghosting cancellation circuitry

Improvement of high contrast interference

GCLK multiplier technology

Dual refresh mode support

Maximum data clock frequency: 30MHz@VDD=5V

Maximum grey scale clock frequency: 33MHz@VDD=5V
