MBI5170
8-Bit Constant Current LED Sink Driver
with Gain Control
August 2004, VA.00
Features
l
l
Compatible with MBI5168 in package and electrical characteristics
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
8 constant-current output channels
Output current adjustable through an external resistor
Constant output current range: 5 -120 mA
Excellent output current accuracy,
between channels <
±
3% (max.), and
between ICs <
±
6% (max.).
Constant output current invariant to load voltage change
Fast response of output current,
OE (min.): 200 ns @I
out
< 60mA
OE (min.): 400 ns @I
out
= 60~100mA
25MHz clock frequency
Schmitt trigger input
3.3V~ 5V supply voltage
256-step run-time programmable output current gain
suitable for white balance application
