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.
