LED171596A SNVSAY2 – OCTOBER 2017 LED171596A 96-LED Matrix Driver for RGB and White LEDs 1 1 Features 1 • 24 High-Precision Current Sinks – 60-mA Peak Current per Channel – Current Matching ±5% – Independent 9-Bit Duty Cycle PWM and 8-Bit LED Current Control – 7-V Tolerant – ISET Resistor to Set Global Current – Ghosting Cancellation • Four Low Resistance High Side Series Switches – 1.5-A Current-Rated PMOS • I2C, SPI, and PWM Brightness Control Modes • Extensive Protection Features – Open and Shorted LED Fault Detection – Thermal Shutdown Protection 2 Applications • Control Panel Illumination • Local Dimming LED Backlight Drivers 3 Description The LED171596A is an LED driver that can individually control up to 96 LEDs. The driver has 9- bit duty cycle and 8-bit current control of each low- side LED current sink. Each current sink can be individually controlled through the I2C-compatible or SPI interface. The individual LED brightness is internally multiplied with a global brightness register value. This allows the control of all the LEDs at once with a single register or PWM input signal. This global brightness control also passes through a brightness sloper function to create optically smooth brightness transitions without the need for multiple register writes.
