Overview
The A4916KJPTR-T is a fully integrated multiphase motor driver designed for brushless DC (BLDC) motors. It integrates control logic, gate drivers, and power MOSFETs in a single package. The device supports SPI interface communication for configuration and monitoring. It operates within a supply voltage range of 8V to 35V. The component is housed in a 48-LQFP-EP (7x7mm) surface-mount package with an exposed pad for thermal management.
Feature Summary
- Fully integrated multiphase BLDC motor driver with built-in power MOSFETs
- SPI interface for digital control and status monitoring
- Designed for automotive applications with ASIL capability
- Integrated bootstrap supply circuit management
Applications
- Automotive cooling fan systems
- Electric power steering actuators
- Thermal management pumps in electric vehicles
- Industrial multiphase motor control
Procurement Notes
Verify the specific suffix and tape/reel specifications against the manufacturer's latest datasheet before ordering. Confirm that the 48-LQFP-EP package dimensions match your PCB footprint requirements. Ensure compatibility with the required SPI protocol implementation in your host controller design.
Selection Notes
Select this component when a compact, high-integration solution for BLDC motor control is required. It is suitable for designs needing SPI-based configuration rather than analog PWM inputs. Consider the thermal performance of the exposed pad layout for high-current applications. Verify ASIL requirements align with the specific variant selected.
Part Context
This part belongs to Allegro's A4916 family of multiphase motor drivers. It is distinct from the AMT49100 series which targets higher voltage 80V systems. The A4916 is optimized for 12V/24V automotive architectures. It differs from simpler half-bridge drivers by integrating full three-phase drive capabilities.
Replacement Considerations
Check for direct pin-to-pin replacements within the A4916 family. Verify if the A4916KJPTR-T-2 variant offers necessary updates. Cross-reference with older A4916 versions for software compatibility.
