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

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.
