The MCT8329A provides a single-chip, code-free sensorless trapezoidal solution for applications requiring high speed operation or very fast startup time for three phase brushless-DC motors. The device provide three half-bridge gate drivers, each capable of driving high-side and low-side N-channel power MOSFETs. The device generates correct gate drive voltages using an internal charge pump and enhances the high-side MOSFETs using a bootstrap circuit. A trickle charge pump is included to support 100% duty cycle. The gate drive architecture supports peak gate drive currents up to 1-A source and 2-A sink. The MCT8329A can operate from a single power supply and supports a wide input supply range of 4.5 to 60 V. Sensorless trapezoidal control is highly configurable through register settings in a non-volatile EEPROM (MCT8329A1I) ranging from motor start-up behavior to closed loop operation, which allows the device to operate stand-alone once it has been configured. Motor current is sensed using an integrated current sensing amplifier supporting single external shunt resistor. The device receives a speed command through a PWM input or analog voltage or variable frequency square wave or I2C command. There are a large number of protection features integrated into the MCT8329A, intended to protect the device, motor, and system against fault events. https://elecena.pl/product/30540305/60-v-sensorless-trapezoidal-control-three-phase-bldc-gate-driver-ree-36-40-to-125 2026-07-30 https://elecena.pl/product/30540305/60-v-sensorless-trapezoidal-control-three-phase-bldc-gate-driver-ree-36-40-to-125 2026-10-06
