The MCT8316Z provides a single-chip code-free sensored trapezoidal solution for customers driving 12- to 24-V brushless-DC motors. The MCT8316Z integrates three 1/2-H bridges with 40-V absolute maximum capability and a very low RDS(ON) of 95 mOhms (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 of an adjustable buck regulator and LDO generate the necessary voltage rails for the device and can be used to power external circuits.

MCT8316Z implements sensored trapezoidal control in a fixed-function state machine, so an external microcontroller is not required to spin the brushless-DC motor. The 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 the MCT8316Z, intended to protect the device, motor, and system against fault events.

Refer Section 9.1 for design consideration and recommendation on device usage.
