UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
The DRV89xx-Q1 is primarily used for the control of multiple brushed DC motors which can be connected in independent-type, sequential-type or the parallel-type motor connection as shown in Figure 134.
An automotive battery powers the device to power supply pin (VM). A 3.3-V regulated power supply is generated for the supplying power to the digital core (VDD) of the device. A micro-controller is connected to the DRV89XX-Q1 device with the SPI interface (4-lines) for control, configuration and diagnostics. The device operating or sleep state is controlled by the nSLEEP pin and nFAULT pins is used as an additional hardware diagnostics.
