The STP1612PW05 is a 16-channel constant current sink LED driver. The maximum output current value for all the 16 channels is set by a single resistor from 3 mA to 60 mA. The device features 8-bit gain (256 steps) for global LED brightness adjustment with two selectable ranges. This function is accessible via a serial interface. The device has an individual adjustable PWM brightness control for each output channel. The PWM counters are selectable via a serial interface with 4096 or 65536 steps (12 or 16 bit). The STP1612PW05 also provides enhanced pulse-width modulation counting algorithms called e-PWM to reduce flickering effects (ghost visual effects) improving the overall image quality. The device has a dual size 16-bit or 256-bit shift register. All the control and the shift register read back data are accessible via serial interface. The STP1612PW05 has the capability to detect open and short LED failure and overtemperature, reporting the status through SPI line. The device guarantees a 20 V output driving capability, allowing the user to connect more LEDs in series.
