3 Description

The DRV10987 device is a 3-phase sensorless 180°

sinusodial motor driver with integrated power

MOSFETs, which can provide continuous drive

current up to 2 A. The device is specifically designed

for cost-sensitive, low-noise, low-external-componentcount fan and pump applications.™

The DRV10987 device delivers current to the motor

with supply voltage as low as 6.2 V. If the power

supply voltage is higher than 28 V, the device stops

driving the motor and protects the DRV10987

circuitry.
