SLOSE79B August 2022 – October 2023 DRV8462
PRODUCTION DATA
The DRV8462 can operate with hardware (H/W) pin interface or SPI interface. When operating with SPI interface, the device supports additional features and detailed diagnostics, as shown in Table 7-4.
The logic-level MODE pin latches the operating interface information at power up or after nSLEEP cycling -
If the MODE pin is grounded at this time, the device operates with H/W pin interface.
If the MODE pin is logic high at this time, the device operates with SPI interface.
Do not change MODE pin logic level on the fly after power up or after nSLEEP = 1.
The functionality of five pins depend on the interface of operation, as shown in Table 7-2 and Table 7-3 -
