IS31FL3746A-QFLS4-TR
18 x 4 Dots Matrix LED Driver with 8-bit PWM and 8-bit Dot Correction
The IS31FL3746A is a general purpose 18×n (n=1~4) LED Matrix driver programmed via a 1MHz I2C compatible interface. Each of the 72 LEDs can be dimmed individually with 8-bit PWM data and 8-bit DC scaling data for color calibration. It features individual open and short error detection, 180-degree phase delay to reduce power noise, and spread spectrum technology to optimize EMI performance. The device operates from a 2.7V to 5.5V supply voltage range.
Temp Range-40 to +125°C
