Texas Instruments DRV8908-Q1 | Demoboard DRV8908-Q1EVM

Description

The DRV8908-Q1 evaluation module (EVM) is an application board design to allow easy evaluation of the DRV8908-Q1 device. The DRV8908-Q1 device is an integrated 4.5-V to 32-V 8 channel H-bridges for automotive applications such as control of heating, ventilation, and airconditioning (HVAC) flap DC motor.A standard 16-bit serial peripheral interface (SPI) provides a simple method for configuring the various device settings and reading fault diagnostic information through an external controller. For more information on this evaluation module please refer to the DRV89xx-Q1EVM User's Guide.
