MBI5029
16-Bit Constant Current LED Sink Driver
with Error Detection and Current Adjust
Features
z Compatible with MBI5026 in electrical characteristics and package
z 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
z 16 constant-current output channels
z Constant output current invariant to load voltage change
z Constant output current range: 5 -90 mA
z Excellent output current accuracy,
between channels: < ±3% (max.), and
between ICs: < ±6% (max.)
z Output current adjusted through an external resistor
z 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
z Fast response of output current,
OE (min.): 200 ns
z 25MHz clock frequency
z Schmitt trigger input
z 5V supply voltage
z Optional for “Pb-free & Green” Package

effective current IOUT, effective to the target current IOUT, target defined by Rext. If IOUT, effective is less than the
target current IOUT, target, an error flag(Low) will be asserted and stored into the built-in Shift Register. The
minimum voltage requirement for such current detection is VDS, Th1, VDS, Th2, VDS, Th3 and VDS, Th4.
