Product Description

MBI5025 is designed for LED displays. As an enhancement of its predecessor, MBI5016,

MBI5025 exploits PrecisionDrive™ technology to enhance its output characteristics. MBI5025 contains a serial buffer and data latches which convert serial input data into parallel output format. At MBI5025 output stage, sixteen regulated current ports are designed to provide uniform and constant current sinks for driving LEDs within a large range ofVf variations.

Features

• 16 constant-current output channels

• Constant output current invariant to load voltage change：

Constant output current range: 3-50 mA

• Excellent output current accuracy:

between channels: ±3 (max.), and

between ICs: ±6 (max.)

• Output current adjusted through an external resistor

• Fast response of output current, OE (min.): 400 ns

• 25MHz clock frequency

• Schmitt trigger input

• 3.3V / 5V supply voltage
