Key Features
- Sensorless sinusoidal commutation with integrated back-EMF detection eliminates Hall-effect sensors, reducing system BOM cost
- 12 V to 24 V supply range with 3.5 A peak phase current supports a broad range of fan and pump motor sizes
- Integrated gate drivers and power MOSFETs in a compact WQFN package minimize external component count and PCB footprint
Applications
The DRV10987SPWP is designed for quiet, efficient sensorless BLDC motor control in home appliances such as refrigerator fans, air purifiers, and ventilation blowers. Its sinusoidal drive algorithm reduces acoustic noise compared to trapezoidal commutation, making it ideal for noise-sensitive consumer environments. The device also suits industrial cooling and pump applications requiring continuous 24 V operation with minimal external circuitry.

Frequently Asked Questions
What supply voltage range and peak current capability does the DRV10987SPWP support?
The DRV10987SPWP operates from 6 V to 28 V (12 V to 24 V nominal) and delivers up to 3.5 A peak phase current, covering a wide range of small BLDC motors used in fans, pumps, and appliance drives without external gate driver ICs.
How does the DRV10987SPWP achieve sensorless motor control, and what startup method does it use?
The device uses proprietary back-EMF detection across all 3 phases to track rotor position without Hall sensors, and employs an open-loop align-and-go startup sequence configurable via SPI registers to reliably spin motors from 0 RPM under load.
Which fan and pump applications are best matched to the DRV10987SPWP?
The DRV10987SPWP targets 12 V to 24 V axial and centrifugal fans in HVAC units, refrigerator evaporator and condenser fan motors, and small centrifugal water pumps requiring continuous duty at up to 3.5 A, where low audible noise from sinusoidal commutation is a design priority.
When is the DRV10987SPWP a better choice than the DRV10983 for a new BLDC design?
The DRV10987SPWP adds an SPI configuration interface, programmable current limit, and advanced startup parameter tuning absent in the DRV10983, making it preferable for designs needing in-system tuning or where motor parameters vary across production lots by more than ±20%.
What protection features are integrated in the DRV10987SPWP?
The DRV10987SPWP integrates overcurrent protection at 3.5 A, thermal shutdown at approximately 150°C junction temperature, undervoltage lockout below 6 V, and lock-detection with automatic restart after a stall event, reducing the need for external protection circuits in 24 V fan systems.
