DRV10987PWPR

Overview

The DRV10987PWPR is a three-phase sensorless BLDC motor driver from Texas Instruments, designed for 12V to 24V nominal systems. It integrates power MOSFETs with an RDS(on) of 250mΩ and delivers up to 2A continuous current (3A peak). Operating on a 6.2V to 28V supply range, it features I2C control, PWM input, and FG feedback. The device includes integrated 5V buck and 3.3V LDO regulators, supports EEPROM customization, and operates within a -40°C to +125°C temperature range in a 24-pin HTSSOP package.

Feature Summary

• Integrates 180-degree sinusoidal commutation with proprietary sensorless control to minimize acoustic noise
• Features flexible user interfaces including I2C for register access and dedicated SPEED/FG pins
• Includes integrated 5V buck converter and 3.3V LDO to reduce external component count
• Provides comprehensive protection against overcurrent, rotor lock, voltage surges, and thermal events

Applications

• Floor fans and ceiling fans
• Air purifiers and humidifiers
• Dryer circulation fans
• Drainage and water pumps

Procurement Notes

Verify the specific suffix matches the required standby or sleep mode variant, as the base DRV10987 family includes distinct versions like DRV10987S and DRV10987D with different power consumption profiles. Confirm the HTSSOP-24 package availability and ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification. Cross-reference the exact ordering part number with manufacturer documentation to avoid functional mismatches regarding interface or power states.

Selection Notes

Select this component for cost-sensitive applications requiring low noise and minimal external circuitry. The integrated power stage and regulators simplify design compared to discrete solutions. Ensure the motor load aligns with the 2A continuous current limit and that the system voltage falls within the 6.2V to 28V operating window. Consider the I2C interface requirements for system integration and verify thermal management capabilities given the exposed pad package design.

Part Context

The DRV10987 belongs to Texas Instruments' portfolio of three-phase motor drivers targeting home appliance and industrial pump markets. It replaces older discrete designs by combining control logic, gate drivers, and power MOSFETs into a single chip. This integration reduces board space and improves reliability by minimizing interconnect points between high-current paths and control circuits.
