The DRV10987 device provides a sleep version and a standby version. The DRV10987 part number is used for both devices, that is, DRV10987D (sleep version), DRV10987S (standby version). When the device enters either sleep or standby, the device stops driving the motor. The step-down regulator is disabled in the sleep mode version to conserve more energy. The I²C interface is disabled and any register data not stored in EEPROM is reset for the sleep mode version. The switching regulator remains active in the standby mode version. The register data is maintained, and the I²C interface remains active for the standby mode version. Table 1-1 shows the differences between DRV10987D sleep mode and DRV10987S standby mode.
