Product Overview
The DRV10974 is a Texas Instruments three-phase sensorless BLDC motor driver in the Power_Management category. It integrates the drive and control functions needed for 180° sinusoidal commutation without position sensors, with a 4.4 V to 18 V operating supply range and 750 mOhm typical total driver on-resistance at TA = 25°C.
Drive capability is specified at 1 A rms continuous phase current and 1.5 A peak phase current. Speed control is provided through a PWM pin that auto-detects analog or digital mode, while the open-drain FG output provides speed feedback with an internal pullup to V3P3. Direction is selected by the FR pin, supporting U-to-V-to-W or U-to-W-to-V phase sequencing.
Assembly and configuration use external passive components. ADV selects lead angle with a 1/8-W resistor, CS selects current limit with a 1/8-W resistor, and RMP sets the acceleration ramp rate through a 1/8-W resistor to GND. Required capacitors include 10 uF from VCC to GND, 100 nF from VCP to VCC, and 1 uF on the V1P8 LDO output, which can support up to 3 mA external load.
