General Description

The MLX10801 is a multi-purpose LED driver for high power LEDs designed for automotive applications. A lot of adjustment possibilities allow for the design of different LED applications using only a few external components.

The circuit is load dump protected for a 40V load dump pulse.

As a second use, a variety of coils like relays and micro valves can be driven in a very efficient power saving mode.

A third use is a simple electronic fuse, to protect circuits from overcurrent or overtemperature.

Features

General

• Minimum number of inexpensive external components

• Auto shutdown in case of over temperature with internal or external temperature sensor

• Small package allows compact module design with minimised wire runs and short connections to achieve improved EMI performance

• MLX10801 is offered in 2 package options: SOIC8 and MLPD8 5x5. The MLPD8 5x5 package option allows to take out a higher peak and average current than the SOIC8 package option
