Overview
The MCT8315Z0HRRYR is a three-phase brushless DC (BLDC) motor driver from Texas Instruments, designed for sensor-based trapezoidal control. It integrates three half-bridges with a low RDS(ON) of 275mΩ and supports a supply voltage range of 4.5V to 35V. The device features an integrated current limit, eliminating external sense resistors, and includes configurable PWM modulation up to 200kHz. It provides built-in protection mechanisms such as overcurrent, overvoltage, and thermal shutdown.
Feature Summary
- Integrates three half-bridges for high-power BLDC motor driving
- Supports sensor-based trapezoidal commutation via analog or digital Hall inputs
- Includes integrated current limiting to remove external detection components
- Features comprehensive fault protection including overcurrent and thermal shutdown
Applications
- 12V/24V brushless DC motor systems
- Industrial automation actuators
- Automotive cooling fans and pumps
Procurement Notes
Verify the specific suffix '0HRRYR' against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and logic levels before integration into the design.
Selection Notes
Select this component when a single-chip solution for sensor-based BLDC control is required. It is suitable for applications needing integrated power stages and protection without an external microcontroller. Consider the available configuration options via hardware pins versus SPI interface based on system complexity.
Part Context
This part belongs to the MCT8315Z family of three-phase BLDC motor drivers. The family offers various configuration options, including hardware-pin based setups and SPI interfaces, catering to different application requirements for motor control simplicity and flexibility.
Replacement Considerations
Consult official substitution lists for equivalent devices within the MCT8315Z series or compatible TI motor drivers. Verify pinout and electrical characteristics match before replacing.
