3 Description

The DRV3205-Q1 bridge driver is dedicated to automotive three-phase brushless DC motor control applications. The device provides six dedicated drivers for standard-level N-channel MOSFET transistors. A boost converter with an integrated FET provides the overdrive voltage, allowing full control on the power stages even for low battery voltage down to 4.75 V. The strong driver strength is suitable for high-current applications and programmable to limit peak output current.

The device incorporates robust FET protection and system monitoring functions like a Q&A watchdog and voltage monitors for I/O supplies and ADC reference voltages. Integrated internal diagnostic functions can be accessed and programmed through an SPI interface.
