Description
The Atmel LED DriversMSL3163 and MSL3164 compact, high-power LED string drivers use internal current control MOSFETs to sink up to 100mA per string, with current accuracy and matching better than 3%. The MSL3163/4 drive 16 parallel strings of ten white LEDs each, for a total of 160 white LEDs per device.
Key Features
- a 20 MHz SPI serial interface, and the MSL3163 offers a 1 MHz I2C serial interface
- Both interfaces support video frame-by-frame LED string intensity control for up to 16 interconnected devices to allow active area dimming
- Additionally, an on-chip E²PROM allows the power-up defaults to be customized through the serial interface
- Global string drive pulse width is adjusted with an 8-bit global intensity register, and individual string pulse width is modulated with 1
