IPS7091PBF Equivalent & Substitute Parts

Part Overview

The IPS7091PBF is a high-side power switch driver manufactured by Infineon Technologies, designed for load switching applications in the 6V to 35V range with a maximum output current of 1.5A. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The part is packaged in TO-220AB (5-LEAD) through-hole configuration and features an 80mOhm typical on-resistance with non-inverting input control.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IPS7091PBF is determined by the following critical electrical and mechanical parameters:

• Output Configuration & Type: High-side switching with N-channel output topology
• Load Voltage Range: 6V to 35V compatibility
• Output Current Capability: 1.5A maximum rating
• On-Resistance: 80mOhm typical specification
• Input Control: Non-inverting logic interface
• Temperature Range: -40°C to 150°C operating window
• Manufacturer Continuity: Infineon Technologies base product family

The AUIPS7091GTR qualifies as a direct substitute based on matching all critical electrical parameters. While the package format differs (surface-mount DSO-8 versus through-hole TO-220AB), the functional electrical specifications remain equivalent, enabling substitution in applications where package transition is feasible.

Engineering Selection Recommendations

The AUIPS7091GTR is an active-status substitute for the obsolete IPS7091PBF, with identical electrical performance across all critical parameters. Selection of AUIPS7091GTR is supported by:

• Matching load voltage range (6V ~ 35V)
• Equivalent output current specification (1.5A maximum)
• Identical on-resistance characteristic (80mOhm typical)
• Consistent operating temperature range (-40°C ~ 150°C)
• Automotive-grade qualification (AEC-Q100) with enhanced reliability features
• ROHS3 compliance and REACH unaffected status

The primary design consideration is the transition from through-hole TO-220AB packaging to surface-mount 8-SOIC packaging, which requires PCB layout modification and assembly process adjustment. The AUIPS7091GTR includes additional fault protection features (current limiting, open load detect, over-temperature protection) and auto-restart functionality not specified in the original part.

Frequently Asked Questions (FAQ)

Q: Can AUIPS7091GTR directly replace IPS7091PBF without circuit modification?

A: Electrical substitution is valid based on matching voltage, current, on-resistance, and input control specifications. However, package format differs (surface-mount versus through-hole), requiring PCB redesign and assembly process changes.

Q: What are the key electrical parameters that define substitution compatibility?

A: Load voltage range (6V ~ 35V), maximum output current (1.5A), on-resistance (80mOhm typical), input logic type (non-inverting), and operating temperature range (-40°C ~ 150°C) are the primary criteria.

Q: Why is AUIPS7091GTR classified as active while IPS7091PBF is obsolete?

A: AUIPS7091GTR represents the current-generation product within the Infineon IPS7091 family, with automotive qualification and enhanced protection features. IPS7091PBF has been discontinued from the manufacturer's active product line.

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

A: AUIPS7091GTR carries AEC-Q100 automotive qualification and ROHS3 compliance. Both parts maintain REACH unaffected status and EAR99 export classification.

Q: What packaging considerations apply to substitution?

A: IPS7091PBF uses TO-220-5 through-hole packaging suitable for manual or wave soldering. AUIPS7091GTR uses 8-SOIC surface-mount packaging requiring reflow soldering and PCB pad redesign. Thermal management characteristics may differ due to package geometry.
