MBI1801GSD Description

Short technical summary and product information.

The Macroblock MBI1801GSD is an All-Ways-On™ High-Power LED Driver designed for high-flux LED lighting applications. It provides a constant output current that is invariant to supply and load voltage changes, ensuring consistent LED performance.

 

The device allows users to adjust the output current from 50 mA up to a maximum of 1.2A using an external resistor (Rext), offering flexibility in controlling LED brightness. Additionally, LED brightness can be precisely controlled from 0% to 100% via the output enable (OE) pin using Pulse Width Modulation.

 

For system reliability, the MBI1801GSD incorporates built-in thermal protection that safeguards the IC from over-temperature conditions, typically tripping at 165°C. The driver supports cascading LEDs up to a maximum of 17V at the output port. It is supplied in a TO-265 package, suitable for surface mounting, which enhances power dissipation capabilities.

 

Key features include a 5V supply voltage, constant output current control, and adjustable current via an external resistor. The "Pb-free" package indicates compliance with environmental standards.
