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.
