EVAL-L9301 STMicroelectronics

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. This kit includes L9301 Demo Board Firmware Features for SPC560P-DISP Graphical User Interface developed in LabView environment Operating battery supply voltage: 5V - 18V Documentation, Demo board and GUI user Operating Vdd supply voltage: 4.75V - 5.25V manual.
