Datasheet
MBI5029
16-Bit Constant Current LED Sink Driver
with Error Detection and Current Adjust
April 2005, VA.02
Features
Compatible with MBI5026 in electrical characteristics and package
Exploiting Share-I-O™ technique to provide two operation modes:
- Normal Mode with the same functionality as MBI5026
- Special Mode to detect individual LED errors, like MBI5027
and program output current gain, like MBI5028
16 constant-current output channels
Constant output current invariant to load voltage change
Constant output current range: 5 -90 mA
Excellent output current accuracy,
between channels: < ±3% (max.), and
between ICs: < ±6% (max.)
Output current adjusted through an external resistor
128-step programmable output current gain for White Balance,
low current band: gain = 1/9 ~ 95/288, linearly divided into 64 steps
high current band: gain = 1/3 ~ 95/96, linearly divided into 64 steps
Fast response of output current,
OE
(min.): 200 ns
