5 Description (Continued)
The DRV10987 device uses a proprietary sensorless control scheme to provide continuous sinusoidal drive,
which significantly reduces the pure tone acoustics that typically occur as a result of commutation. The interface
to the device is designed to be simple and flexible. The motor can be controlled directly through PWM, analog, or
I²C inputs. Motor speed feedback is available through both the FG pin and the I²C interface simultaneously.
The DRV10987 device features an integrated buck regulator to step down the supply voltage efficiently to 5 V for
powering both internal and external circuits. The 3.3-V LDO also may be used to provide power for external
circuits.
An I²C interface allows the user to reprogram specific motor parameters in registers and to program the
EEPROM to help optimize the performance for a given application. The DRV10987 device is available in a
thermally-efficient HTSSOP, 24-pin package with an exposed thermal pad. The operating ambient temperature is
specified from –40°C to 125°C.
