Description

The EVAL-L9301 is an Evaluation Board

designed to evaluate L9301, a smart power

device mainly for ABS valves applications.

L9301 is able to drive electronic on-off valves with

or without external freewheeling diode.

The OUT1-8 can be driven by parallel input in

PWM mode or SPI command. Through the SPI it

is possible to configure the device parameters like

configuration, Slew-rate, Overcurrent threshold,

to send the drivers EVAL-L9301 commands and

to read back the diagnosis results.

The device is protected against over temperature,

open load, short to GND and short to Vbattery

condition. The overcurrent diagnostics can be set

in latched or unlatched mode for each channel.

This kit includes L9301 Demo Board; Firmware

for SPC560P-DISP; Graphical User Interface

developed in LabView environment

Documentation, Demo board and GUI user

manual.
