Texas Instruments MCT8315A
The MCT8315A provides a single-chip, codefree sensorless trapezoidal solution for customers requiring high speed operation (up to 3 kHz electrical) or very fast start-up time (< 50 ms) for 12- to 24-V brushless-DC motors requiring up to 4-A peak current. The MCT8315A integrates three ½-bridges with 40V absolute maximum capability and a low RDS(ON) of 240 mΩ (high-side + low-side FETs). The MCT8315A receives a speed command through a PWM signal, analog voltage, variable frequency square wave or I2C instruction.| Part No. | MCT8315A |
