TPS2550DRVRG4 Equivalent & Substitute Parts

Part Overview

The TPS2550DRVRG4 is a Power Management IC (PMIC) functioning as a general-purpose N-Channel power switch/driver with 1:1 input-output ratio and high-side output configuration. Manufactured by Texas Instruments, this component delivers 1.1A maximum output current in a compact 6-WSON (2x2) surface-mount package. The part is currently discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design support and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS2550DRVRG4 is determined by the following critical parameters:

• Output Type & Configuration: N-Channel, High Side output
• Ratio: 1:1 input-output
• Current Rating: 1.1A maximum output
• Voltage Range: 2.5V ~ 6.5V load voltage
• On-Resistance: 100mOhm typical
• Package: 6-WSON (2x2) form factor
• Interface: On/Off control, Non-Inverting input
• Fault Protection: Current Limiting (Adjustable), Over Temperature, UVLO

Parametric equivalents maintain identical electrical specifications and package footprint. The MIC2019YML-TR represents a manufacturer-recommended alternative with functional equivalence but differs in output type (P-Channel vs. N-Channel) and current rating (2A vs. 1.1A), requiring circuit-level evaluation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents: TPS2550DRVT and TPS2551DRVT are parametric equivalents of the TPS2550DRVRG4, maintaining identical electrical specifications, output type, current rating, and thermal operating range. Both are ROHS3 compliant. The primary distinction is packaging format: TPS2550DRVT and TPS2551DRVT are supplied in Tape & Reel (TR) configuration versus the original DRVRG4 packaging. Both parts carry "Not For New Designs" status, indicating limited long-term availability.

Manufacturer-Recommended Alternative: MIC2019YML-TR from Microchip Technology is designated as a manufacturer-recommended substitute. This component maintains 1:1 ratio, high-side output configuration, and identical package footprint. However, critical differences exist: MIC2019YML-TR features P-Channel output (versus N-Channel), delivers 2A maximum current (versus 1.1A), operates at reduced maximum load voltage (2.5V ~ 5.5V versus 2.5V ~ 6.5V), and has lower on-resistance (70mOhm versus 100mOhm). MIC2019YML-TR carries Active product status and ROHS3 compliance, supporting long-term design continuity.

Selection between parametric equivalents and the manufacturer-recommended alternative depends on circuit topology requirements. N-Channel output designs require TPS2550DRVT or TPS2551DRVT. P-Channel topologies or designs tolerating higher current capability and lower voltage maximum may utilize MIC2019YML-TR.

Frequently Asked Questions (FAQ)

Q: Can TPS2550DRVT directly replace TPS2550DRVRG4 in existing designs?

A: TPS2550DRVT is a parametric equivalent with identical electrical specifications and package footprint. The primary difference is packaging format (Tape & Reel versus original packaging). Direct PCB-level substitution is supported without circuit modification.

Q: What is the key difference between TPS2550DRVT and TPS2551DRVT?

A: Both parts are parametric equivalents with identical electrical performance and thermal ratings. The distinction is the base product number (TPS2550 versus TPS2551), reflecting different design revisions. Both maintain compatibility with TPS2550DRVRG4 applications.

Q: Why does MIC2019YML-TR have different output type (P-Channel vs. N-Channel)?

A: MIC2019YML-TR is a manufacturer-recommended alternative addressing the discontinued status of the TPS2550DRVRG4. The P-Channel output reflects Microchip's design approach for high-side switching. Circuit topology must accommodate this difference; direct pin-for-pin substitution is not supported without circuit redesign.

Q: Is MIC2019YML-TR suitable for 6.5V load voltage applications?

A: No. MIC2019YML-TR maximum load voltage is 2.5V ~ 5.5V, whereas TPS2550DRVRG4 supports 2.5V ~ 6.5V. Applications requiring 6V or 6.5V operation must use TPS2550DRVT or TPS2551DRVT.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TPS2550DRVT, TPS2551DRVT, and MIC2019YML-TR are all ROHS3 compliant, matching the original TPS2550DRVRG4 compliance status.

Q: What is the thermal operating range difference between alternatives?

A: TPS2550DRVRG4, TPS2550DRVT, and TPS2551DRVT operate from -40°C to 150°C (junction temperature). MIC2019YML-TR operates from -40°C to 85°C (ambient temperature). Applications requiring extended high-temperature operation above 85°C ambient must use Texas Instruments alternatives.

Q: Can higher current rating of MIC2019YML-TR (2A vs. 1.1A) be used in TPS2550DRVRG4 designs?

A: MIC2019YML-TR's 2A rating provides additional current margin but does not directly substitute without circuit evaluation. The P-Channel output topology differs fundamentally from N-Channel designs. Circuit-level compatibility assessment is required.
