MBI5170 - 8-Bit Constant Current LED Sink Driver

General Description

MBI5170 succeeds MBI5168 and also exploits PrecisionDrive™ technology to enhance its output characteristics.

Key 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 invari.
