Description

The MCT8376Z-Q1 provides a single-chip code-free sensored trapezoidal control for driving 4.5V to 65V brushless-DC motors. The MCT8376Z-Q1 integrates three 1/2-H bridges with 70V absolute maximum voltage capability and a very low RDS(ON) of 400mΩ (high-side and low-side combined) to enable high power drive capability. Current is sensed using an integrated current sensing feature which eliminates the need for external sense resistors. Power management features with integrated LDO generate the necessary voltage rails for the device and can be used to power external circuits.

MCT8376Z-Q1 implements sensored trapezoidal control in a fixed-function state machine, so an external microcontroller is not required to spin the brushless-DC motor. The MCT8376Z-Q1 device integrates three analog hall comparators for position sensing to achieve sensored trapezoidal BLDC motor control. The control scheme is highly configurable through hardware pins or register settings ranging from motor current limiting behavior to fault response. The speed can be controlled through a PWM input.

There are a large number of protection features integrated into MCT8376Z-Q1, intended to protect the device, motor, and system against fault events.
