PRODUCTION DATA. DRV10987 SLVSE89A – AUGUST 2017 – REVISED NOVEMBER 2017 DRV10987 12- to 24-V, Three-Phase, Sensorless BLDC Motor Driver 1 1 Features 1 • Operation Voltage Range: – Motor Operation, 6.2 V to 28 V • Total Driver H + L rDS(on) – 250 mΩ at TA = 25°C • Drive Current: 2-A Continuous Winding Current (3-A Peak) • Sensorless Sinusoidal 180° Commutation Scheme • Configurable Output PWM Slew Rate and Frequency for EMI Management • Initial Position-Detect Algorithm to Avoid Back- Spin During Start-Up • No External Sense Resistor Required • Flexible User Interface Options: – I2C Interface: Access Registers for Command and Feedback – Dedicated SPEED Pin: Accepts Either Analog or PWM Input – Dedicated FG Pin: Provides TACH Feedback – Spin-Up Profile Can Be Customized With EEPROM – Forward-Reverse Control With DIR Pin • Integrated Buck Converter, 5 ‑V, 100-mA • Integrated LDO, 3.3 ‑V, 20-mA • Standby Current, 8.5-mA • Supply Current of 8.5 mA With Standby Version (DRV10987S) • Supply Current of 48 μA With Sleep Version (DRV10987D) • Protection Features – Overcurrent Protection (Phase-to-Phase, Phase-to-GND and Phase-to-VCC Short Circuits) – Lock Detection to Detect Rotor Lock Condition – Anti-Voltage Surge (AVS) Protection – Undervoltae Lockout (UVLO) – Overvoltage Protection – Thermal Warning and Shutdown • Thermally Enhanced Package 2 Applications • Pedestal and Ceiling Fans • Air Purifiers and Humidifiers • Dryer Circulation Fans • Drain and Water Pumps • Three-Phase BLDC and PMSM Motors 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-component- count 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.
