Using the LED171596AEVM Evaluation Module
The Texas Instruments LED171596A evaluation module (EVM) helps designers evaluate the operation
and performance of the LED171596A 96-LED driver. The LED171596A is an LED matrix driver that can
individually control up to 96 LEDs. To control the 96 LEDs it uses four high-side PMOS switches and 24
low-side programmable current sinks. The driver has 9-bit duty cycle and 8-bit current control of each low
side LED current sink. They can be individually controlled through the I2C-compatible or SPI interface.
The EVM contains one LED171596A (see
