Product Overview
The DRV10987 is a Texas Instruments Power_Management IC for sensorless three-phase BLDC/PMSM motor drive. Its commutation scheme is sensorless sinusoidal 180°, and the device integrates MOSFETs with 250 mOhm total high-side plus low-side RDS(on) at TA=25°C. The winding drive capability is specified at 2 A continuous current and 3 A peak current.
The operating VCC range for motor operation is 6.2 to 28 V, while register contents are preserved across a 4.5 to 45 V VCC range. Integrated supply functions include a 5 V step-down regulator rated for 100 mA in buck mode or 5 mA in linear mode, plus a 3.3 V LDO with a 20 mA feature rating and a 5 mA recommended V3P3 output current under the stated condition.
The device is offered in a 24-pin HTSSOP (PWP) package with exposed thermal pad and 7.80 mm x 6.40 mm body. Thermal data includes 36.1°C/W junction-to-ambient resistance and 1.1°C/W junction-to-case bottom resistance. The specified ambient operating range is -40 to 125°C.
