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.
