MPC17529EV Equivalent & Substitute Parts

Part Overview

The MPC17529EV is a bipolar motor driver IC manufactured by NXP USA Inc., designed for battery-powered applications requiring integrated control and power stage functionality. This device operates across a 2.7V to 5.6V supply voltage range and delivers up to 700mA output current, making it suitable for stepper and brushed DC motor control in portable and embedded systems.

The MPC17529EV is classified as obsolete. Due to its discontinued status, identifying functionally equivalent substitute parts is essential for design continuity, production planning, and long-term component sourcing strategies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC17529EV is determined by strict alignment of the following electrical and mechanical parameters:

• Motor control capability (bipolar stepper and brushed DC support)
• Output configuration (half bridge with 4 outputs)
• Parallel interface for control signals
• Output current rating (700mA)
• Supply voltage range (2.7V ~ 5.6V)
• Load voltage range (2V ~ 6.8V)
• Operating temperature range (-20°C ~ 150°C)
• Surface mount technology
• CMOS implementation
• RoHS3 compliance and REACH unaffected status

The MPC17529EJ qualifies as a direct substitute based on identical electrical specifications and compliance certifications. The primary distinction is packaging format: the MPC17529EV uses 20-VMFP, while the MPC17529EJ uses 20-TSSOP with exposed pad.

Parameter Comparison

Engineering Selection Recommendations

Both the MPC17529EV and MPC17529EJ are obsolete products from NXP USA Inc. Selection between these parts is contingent upon PCB layout and packaging constraints rather than electrical performance.

The MPC17529EV employs a 20-VMFP package with a 5.30mm width footprint. The MPC17529EJ uses a 20-TSSOP package with a 4.40mm width footprint and exposed pad, offering a more compact form factor suitable for space-constrained applications.

Both parts maintain identical electrical specifications, compliance certifications (ROHS3, REACH unaffected), and moisture sensitivity ratings. PCB redesign may be required if transitioning between these package formats due to differing pin pitch and thermal pad configurations.

Frequently Asked Questions (FAQ)

Q: Can the MPC17529EJ directly replace the MPC17529EV without circuit modification?

A: Electrical substitution is direct. However, PCB layout modification is required due to package format differences. The MPC17529EV uses 20-VMFP while the MPC17529EJ uses 20-TSSOP with exposed pad. Pin assignments are identical, but footprint dimensions and thermal pad placement differ.

Q: What is the significance of the exposed pad in the MPC17529EJ?

A: The exposed pad in the 20-TSSOP package provides enhanced thermal dissipation compared to the 20-VMFP variant. This is beneficial in applications approaching the 700mA output current limit or operating at elevated ambient temperatures.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 3, 168 hours). Compliance documentation applies uniformly across both variants.

Q: What is the practical implication of the 0.9mm package width difference?

A: The MPC17529EJ's narrower 4.40mm width enables denser PCB layouts in applications with space constraints. This difference is significant only if board real estate is a limiting factor in the design.

Q: Can these parts be used interchangeably in existing designs without testing?

A: Electrical interchangeability is confirmed. Physical interchangeability requires PCB footprint compatibility. Designs using the 20-VMFP footprint cannot accommodate the 20-TSSOP package without layout revision.
