MBI5170
8-Bit Constant Current LED Sink Driver
with Gain Control
Features
z Compatible with MBI5168 in package and electrical characteristics
z Exploit Share-I-O™ technique to provide two operation modes:
Normal Mode with the same functionality as MB5168,
Current Adjust Mode to program output current gain
z 8 constant-current output channels
z Output current adjustable through an external resistor
z Constant output current range: 5 -120 mA
z Excellent output current accuracy,
between channels < ±3% (max.), and
between ICs < ±6% (max.).
z Constant output current invariant to load voltage change
z Fast response of output current,
OE (min.): 200 ns @Iout < 60mA
OE (min.): 400 ns @Iout = 60~100mA
z 25MHz clock frequency
z Schmitt trigger input
z 3.3V~ 5V supply voltage
z 256-step run-time programmable output current gain
suitable for white balance application
z Optional for “Pb-free & Green” Package
