Description

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.
