MBI5039 16-Channel Constant Current LED Sink Driver

MBI5039 is an enhanced 16-channel constant current LED sink driver with smart error detection and output current gain. MBI5039 succeeds MBI5026 and also exploits PrecisionDrive™ technology to enhance the output characteristics. Furthermore, MBI5039 adopts Share-I-O™ technology to be backward compatible with MBI5026, MBI5027 and MBI5029 in pin definition and.

Features

l 16 constant-current output channels Constant output current range: 3~90mA - 8-90mA @ 5V supply voltage - 3-70mA @ 3.3V supply voltage l In-message error detection - Both open-circuit and short-circuit LEDs can be detected - On-the-fly error detection - Data-in, error-out; both errors are merged and coded with zeros l Compulsory error detection - Full panel, data independent - Silent error detection with 0.25mA in 700ns l Settable threshold voltage for LED short-circuit detection l Thermal detection - Over-temperature report (e.g. temp.>150 °C) l 64-step programmable current gain: f.
