Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC17529EJ is determined by the following critical parameters:

Functional Requirements: Motor driver type (bipolar stepper and brushed DC support), output configuration (four half-bridge outputs), and integrated control with power stage functionality.

Electrical Compatibility: Supply voltage range, load voltage range, and output current capacity must meet or exceed the original specification requirements.

Package Compatibility: Surface mount 20-TSSOP package with exposed pad ensures mechanical and thermal compatibility with existing PCB layouts.

Interface Compatibility: Parallel control interface for signal input and motor phase control.

Regulatory Compliance: RoHS3 compliance and automotive-grade qualification where applicable.

The A4990KLPTR-T qualifies as a substitute based on matching functional architecture, package form factor, and regulatory compliance, while offering extended voltage and temperature operating ranges.

Parameter Comparison

Engineering Selection Recommendations

The A4990KLPTR-T serves as the direct substitute for the obsolete MPC17529EJ. Both devices share identical functional architecture, output configuration, and package form factor, enabling direct replacement in existing designs.

The A4990KLPTR-T offers extended operating ranges: supply voltage extends from 0V to 50V (compared to 2.7V to 5.6V), load voltage extends to 50V (compared to 2V to 6.8V), and operating temperature extends to -40°C minimum (compared to -20°C). Output current increases from 700mA to 800mA.

Both parts maintain ROHS3 compliance and are suitable for surface mount assembly. The A4990KLPTR-T carries automotive-grade qualification and active product status, ensuring long-term availability and supply chain stability. The improved MSL rating (2 versus 3) provides better moisture protection during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the A4990KLPTR-T directly replace the MPC17529EJ in existing designs?

A: Yes. Both devices use identical 20-TSSOP package geometry with exposed pad, parallel control interface, and four half-bridge output configuration. Pin-to-pin compatibility and functional equivalence enable direct substitution without PCB redesign.

Q: What are the key differences between these two parts?

A: The primary differences are technology (CMOS versus DMOS), operating voltage ranges (2.7-5.6V versus 0-50V), product status (obsolete versus active), and automotive qualification (standard versus automotive grade). The A4990KLPTR-T provides higher output current (800mA versus 700mA) and extended temperature range (-40°C to 150°C versus -20°C to 150°C).

Q: Is the A4990KLPTR-T suitable for battery-powered applications?

A: Yes. The A4990KLPTR-T supports the 2.7V to 5.6V supply range required for battery-powered designs, with additional capability to operate at higher voltages up to 50V for applications requiring extended voltage flexibility.

Q: Are there any package considerations when substituting these parts?

A: Both parts use 20-TSSOP package with exposed pad. Ensure PCB thermal design accommodates the exposed pad for proper heat dissipation. The A4990KLPTR-T has improved moisture sensitivity level (MSL 2 versus MSL 3), requiring less stringent moisture control during storage.

Q: What compliance certifications apply to both parts?

A: Both the MPC17529EJ and A4990KLPTR-T are ROHS3 compliant and REACH unaffected. The A4990KLPTR-T additionally carries automotive-grade qualification, suitable for automotive and industrial applications requiring enhanced reliability standards.
