Lumissil Microsystems LED Drivers IS31FL3726A-SALS4-TR

The IS31FL3726A-SALS4-TR is a 16-channel LED driver designed for driving common anode LEDs, operating from a supply voltage of 3V to 5.5V. It features constant-current open-drain outputs, with the output current adjustable from 5mA to 60mA using an external resistor. The device utilizes a high-speed 4-wire serial interface capable of data rates up to 30MHz, allowing for efficient control of the LED outputs. Current accuracy is specified at less than ¬±4% for bit-to-bit variations and less than ¬±2% for device-to-device variations when all outputs are active at 25.2mA. The driver supports PWM input for brightness adjustment and is suitable for applications such as video display panels, point of sale signs, and variable LED signboards. The operating temperature range is -40¬8C to +125¬8C, making it suitable for industrial applications. The IS31FL3726A-SALS4-TR is available in a 24-pin SSOP package.
