Overview
The AMT49105KEVTR-J is an automotive-grade BLDC system basis IC manufactured by Allegro MicroSystems. It integrates a three-phase half-bridge power stage with parallel input capability, designed for high-power inductive loads such as BLDC motors. The device supports PWM and SPI interfaces for control and diagnostics. It operates within a supply voltage range of 5.5V to 50V and features an operating temperature range from -40°C to 150°C. The component is housed in a 48-VFQFN package with exposed pad (7x7 mm) and is available in tape and reel packaging.
Feature Summary
- Integrates full motor control logic with a three-phase NMOS power stage for compact system design
- Supports parallel input architecture to reduce external component count and simplify PCB layout
- Includes integrated LIN transceiver for robust communication in automotive environments
- Provides comprehensive diagnostic capabilities and protection features for safety-critical applications
Applications
- Engine cooling fan systems
- Automotive water and oil pumps
- Brake actuator systems
- Safety-critical motor drives requiring ASIL compliance
Procurement Notes
Verify the specific suffix 'J' against the manufacturer's current datasheet to confirm pinout and feature set compatibility. Ensure the 48-QFN package dimensions match the target PCB footprint. Confirm that the parallel input configuration aligns with the host controller's signal availability. Validate that the integrated LIN transceiver meets the required bus speed and voltage levels for the specific application network.
Selection Notes
Select this component when a single-chip solution combining gate driving, control logic, and communication is required for BLDC motors. The parallel input interface reduces GPIO usage on the main microcontroller compared to serial-only drivers. Consider the thermal performance of the 48-QFN package for the expected load current. Verify that the 50V maximum supply voltage covers the system's peak operating conditions without exceeding ratings.
Part Context
This part belongs to the AMT4910x family of automotive motor drivers. It is distinct from the AMT49100 series, which typically utilizes different interface configurations or pinouts. The KEVTR-J designation indicates the specific package type, tape/reel packaging, and regional or feature variants defined by Allegro MicroSystems for mass production.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing with the AMT49100KJPTR-A-5 requires careful verification of interface differences and pin compatibility due to potential architectural variations within the family.
