MIC2044-2BTS Equivalent & Substitute Parts

Part Overview

The MIC2044-2BTS is a Power Management Integrated Circuit (PMIC) functioning as a general-purpose power switch/driver with 1:1 configuration and N-Channel high-side output topology. This device is rated for 6A maximum output current with 20mOhm typical on-resistance and operates across a supply voltage range of 1.6V to 5.5V. The MIC2044-2BTS is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC2044-2BTS is determined by strict equivalence across the following critical parameters:

• Output configuration (High Side, N-Channel, 1:1 topology)
• Maximum output current rating (6A)
• On-resistance specification (20mOhm typical)
• Supply and load voltage ranges (1.6V ~ 5.5V and 0.8V ~ 5.5V respectively)
• Package type (16-TSSOP)
• Fault protection feature set (Current Limiting, Open Load Detect, Over Temperature, Reverse Current, UVLO)
• Operating temperature range (-40°C ~ 85°C)

The MIC2044-2YTS qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction between these parts is packaging format (Bulk versus Tube) and product status (Discontinued versus Active).

Parameter Comparison

Engineering Selection Recommendations

The MIC2044-2YTS is the direct functional equivalent for the discontinued MIC2044-2BTS. Both parts share identical electrical specifications, output current ratings, on-resistance characteristics, voltage operating ranges, and fault protection mechanisms. The MIC2044-2YTS is currently in active production status, ensuring availability for new designs and component replenishment.

A significant compliance distinction exists between these parts: the MIC2044-2BTS is RoHS non-compliant, while the MIC2044-2YTS achieves ROHS3 compliance. For applications subject to RoHS regulatory requirements or customer specifications mandating RoHS compliance, the MIC2044-2YTS is the appropriate selection. The packaging format difference (Tube versus Bulk) does not affect electrical performance or circuit functionality and represents a supply chain consideration only.

Frequently Asked Questions (FAQ)

Q: Can the MIC2044-2YTS be used as a direct replacement for the MIC2044-2BTS in existing designs?

A: Yes. The MIC2044-2YTS provides identical electrical performance, output current capability, on-resistance, voltage ratings, and fault protection features. No circuit modifications are required for substitution.

Q: What is the difference between Bulk and Tube packaging?

A: Bulk and Tube are packaging and delivery formats that do not affect component electrical characteristics or performance. Bulk packaging typically involves loose components in larger quantities, while Tube packaging provides components in organized plastic tubes. Selection depends on procurement and assembly process requirements.

Q: Does the RoHS compliance difference affect circuit performance?

A: RoHS compliance status reflects manufacturing process and material composition standards, not electrical performance. Both parts function identically in circuit applications. RoHS compliance becomes relevant only when regulatory or customer requirements mandate compliance certification.

Q: Are there any pinout or footprint differences between MIC2044-2BTS and MIC2044-2YTS?

A: No. Both parts use the 16-TSSOP package with identical pinout and footprint dimensions (0.173", 4.40mm Width). PCB layouts and component placement require no modification.

Q: What is the operating temperature range for both parts?

A: Both the MIC2044-2BTS and MIC2044-2YTS operate across -40°C to 85°C ambient temperature range, supporting industrial and commercial temperature specifications.
