3 Description

The MCT8315Z provides a single-chip, codefree

sensored trapezoidal solution for customers

driving 12-V/24-V brushless-DC motors; no external

microcontroller is needed to spin the BLDC motor.

The MCT8315Z integrates three ? -bridges with 40-

V absolute maximum capability and a low RDS(ON)

of 275 mΩ (HS+ LS) to enable high power drive

capability. The integrated current limiting feature

limits motor currents during start-up or high load

conditions while eliminating the need for external

sense resistors. MCT8315Z provides an output

voltage adjustable buck regulator and an LDO that

can be used to power external circuits. MCT8315Z

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 advance angle.

The speed can be controlled through a PWM input.

A number of protection features including supply

undervoltage lockout (UVLO), overvoltage protection

(OVP), charge pump undervoltage (CPUV),

overcurrent protection (OCP), over-temperature

warning (OTW) and over-temperature shutdown

(TSD) are integrated into MCT8315Z to protect the

device, motor, and system against fault events. Fault

conditions are indicated by the nFAULT pin.

Refer Application Information for design consideration

and recommendation on device usage.
