EVAL-L9301

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.
