DRV591VFPG4 Equivalent & Substitute Parts

Part Overview

The DRV591VFPG4 is a Thermoelectric Cooler PMIC (Power Management IC) manufactured by Texas Instruments in a 32-HLQFP (7x7) surface mount package. This device functions as a PWM power driver optimized for high-efficiency thermoelectric cooler applications. The DRV591VFPG4 is currently discontinued at DiGi Electronics, making identification of compatible substitute parts essential for ongoing design support and production continuity. The availability of active equivalent parts ensures design flexibility and supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DRV591VFPG4 is determined by strict equivalence across the following critical parameters:

• Package Compatibility: Both main and substitute parts must use the 32-LQFP Exposed Pad package in 32-HLQFP (7x7) form factor to ensure PCB footprint and thermal interface compatibility.
• Electrical Specifications: Supply voltage range (2.8V ~ 5.5V) and operating temperature range (-40°C ~ 85°C) must be identical to maintain circuit performance.
• Regulatory Compliance: RoHS3 compliance and MSL rating (3, 168 Hours) must match to satisfy manufacturing and storage requirements.
• Base Product Series: Both parts share the DRV591 base product number, confirming functional equivalence for thermoelectric cooler applications.

The DRV591VFP substitute part meets all these criteria and represents a direct functional equivalent with improved product status (Active vs. Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The DRV591VFP is the recommended substitute for the discontinued DRV591VFPG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, package geometry, and regulatory compliance certifications. The DRV591VFP maintains Active product status, ensuring long-term availability and supply chain stability. The only difference is packaging format (Tray vs. unspecified), which does not affect functional performance or PCB integration. For applications currently using the DRV591VFPG4, direct substitution with the DRV591VFP is electrically and mechanically valid without design modification.

Frequently Asked Questions (FAQ)

Q: Can the DRV591VFP be used as a direct replacement for the DRV591VFPG4?

A: Yes. Both parts are functionally equivalent with identical electrical specifications (2.8V ~ 5.5V supply, -40°C ~ 85°C operating range), package geometry (32-HLQFP 7x7), and regulatory compliance (ROHS3, MSL 3). The DRV591VFP is a direct substitute with no design changes required.

Q: What is the difference between DRV591VFPG4 and DRV591VFP?

A: The primary difference is product status: DRV591VFPG4 is discontinued at DiGi Electronics, while DRV591VFP is Active. The packaging format differs (unspecified vs. Tray), but electrical and mechanical specifications are identical.

Q: Are there any PCB layout considerations when switching from DRV591VFPG4 to DRV591VFP?

A: No. Both parts use the same 32-LQFP Exposed Pad package in 32-HLQFP (7x7) form factor, ensuring identical PCB footprint and thermal interface compatibility.

Q: Does the DRV591VFP meet the same compliance requirements?

A: Yes. The DRV591VFP is ROHS3 compliant with MSL rating 3 (168 Hours), matching the DRV591VFPG4 specifications.

Q: Why is the DRV591VFPG4 discontinued?

A: Product discontinuation is a manufacturer decision. The DRV591VFP remains Active and serves the same thermoelectric cooler application requirements.
