STMicroelectronics Power Switch IC

The STMicroelectronics L9301 is a SPI (Serial Peripheral Interface) controlled octal channel with 4 high/low and 4 low side drivers with the possibility to use four integrated Power MOS as recirculation diodes for PWM load driving. L9301 contains 12 Power MOS: 4 configurable High/Low side drivers with Ronmax= 0.6 Ω (DRN1-4, SRC1-4), 4 low side drivers with Ronmax= 0.6 Ω (OUT1-4) and 4 low side drivers with Ronmax= 0.3 Ω (OUT5-8). Through the SPI it is possible to configure the device parameters like configuration, Slew-rate, Overcurrent threshold, to send the drivers commands and to read back the diagnosis results.

• Additional PWM inputs for 8 outputs
• Over temperature protection
• Open load, short to GND, short to VB
• Overcurrent diagnostics in latched or unlatched mode for each channel
• Controlled SR for improved EMC behaviour
