AMT49101KJPTR-A-5

Overview

The AMT49101KJPTR-A-5 is an integrated three-phase BLDC motor driver from Allegro MicroSystems, designed for automotive applications. It operates with a supply voltage range of 10V to 80V and supports a 5V logic load interface. The device features a 48-LQFP-EP(7x7) surface-mount package and complies with AEC-Q100 standards. It integrates full control and power stages with SPI interface capabilities.

Feature Summary

• Integrated three-phase half-bridge output configuration for brushless DC motor control
• Supports ASIL functional safety features for automotive reliability
• SPI digital interface for programmable control and diagnostics
• Automotive-grade qualification compliant with AEC-Q100 standards

Applications

• Automotive cooling fan systems
• Electric water pump drives
• Thermal management in 48V vehicle architectures

Procurement Notes

Verify the specific suffix 'A-5' to confirm the 5V logic level compatibility, as other variants exist. Confirm current status as Not Recommended for New Design (NRND) if applicable to long-term supply planning. Ensure the 48-LQFP-EP package footprint matches the target PCB layout requirements.

Selection Notes

Select this component when an integrated solution for high-voltage automotive motors is required. Compare against the AMT49100 series for equivalent parameter performance. Consider the NRND status for new designs and evaluate alternative integrated drivers if long-term availability is critical for the product lifecycle.

Part Context

This part belongs to the AMT49100 family of automotive gate drivers. It shares the core architecture with the AMT49100KJPTR-A-5 but differs in the logic supply voltage specification indicated by the trailing suffix. The family targets robust motor control in harsh automotive environments.

Replacement Considerations

The AMT49100KJPTR-A-5 is documented as a parameter-equivalent substitute. Verify pinout and logic voltage compatibility before substitution.
