The MCT8316Z-Q1 provides a single-chip code-free sensored
trapezoidal solution for customers driving 12-V brushless-DC motors in automotive.
The MCT8316Z-Q1 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-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 MCT8316Z-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 the MCT8316Z-Q1, intended to protect the device, motor, and
system against fault events.
Refer Section 9.1 for design consideration and recommendation on device usage.
