EVAL-L9301
EVAL-L9301 Demo board
Data brief
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.
Features
Operating battery supply voltage: 5V - 18V
Operating Vdd supply voltage: 4.75V - 5.25V
Logic inputs TTLcompatible
SPI interface for outputs control and for
diagnosis data communication
This kit includes L9301 Demo Board; Firmware
for SPC560P-DISP; Graphical User Interface
developed in LabView environment
Documentation, Demo board and GUI user
manual.
