Melexis Microelectronic Systems  

IC specification MLX10801

Power LED driver for automotive applications

Power saving low side coil driver

Electronic fuse

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

LED driver

• High energy efficiency

• Light control via PWM possible

• Light output has a minimized dependency on supply and

temperature variations

• Adjustable LED parameters are stored in an internal

NV memory

Coil driver

• Additional use for driving coils like relays and micro valves in a

power saving mode

• Works with a wide range of coils

Electronic fuse

• Additional use as electronic fuse.

• Fuse current adjust possibility

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.
