The MCT8315Z provides a single-chip, code-free 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 ½ -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.
