MBI5171
8-Bit Constant Current LED Driver with
LED Error Detection and Run-Time Current Adjustment
Features
l Compatible with MBI5168 in electrical characteristics and package
l Exploiting Share-I-O™ technique to provide two operation modes:
- Normal Mode with the same functionality as MB5168
- Special Mode to detect individual LED errors, like MBI5169
and program output current gain, like MBI5170
l 8 constant-current output channels
l Constant output current invariant to load voltage change
l Constant output current range: 5 -120 mA
l Excellent output current accuracy,
between channels: < ±3% (max.), and
between ICs: < ±6% (max.)
l Output current adjusted through an external resistor
l Fast response of output current,
OE (min.): 200 ns @I_out< 60mA
OE (min.): 400 ns @I_out= 60~100mA
l 25MHz clock frequency
l Schmitt trigger input
l 3.3~ 5V supply voltage
l 256-step run-time programmable output current gain
suitable for white balance application
