The IS31FL3758-QFLS4-TR from Lumissil Microsystems is a 48-Channel Matrix LED Driver IC. It requires an input voltage of 2.7-5.5 V and provides an output current of 60 mA, adjustable via three 8-bit global current control registers. This driver supports matrix configurations ranging from 48x1 to 40x9, enabled by external PMOS control for power scanning. It integrates both I²C (up to 1 MHz) and SPI (up to 12 MHz) interfaces for flexible control. This IC features open/short detection, thermal shutdown, and de-ghosting circuitry. It has integrated protection circuits such as over-temperature, over-current, and under-voltage circuits. It offers PWM dimming precision up to 8-bit or 6+2-bit, with a maximum PWM frequency of 260 kHz, and includes group phase shifting and spread spectrum features to reduce audible noise and power ripple. This RoHS-compliant IC is available in a surface-mount package that measures 7 × 7 mm and is ideal for white goods display panels with high brightness and gaming machine applications.
