MIC2045-1BTS Equivalent & Substitute Parts

Part Overview

The MIC2045-1BTS is a Power Management Integrated Circuit (PMIC) functioning as a power switch/driver with 1:1 N-Channel configuration, rated for 6A output current. This component is designed for high-side switching applications requiring on/off control with integrated fault protection mechanisms including current limiting, open load detection, over-temperature protection, and reverse current blocking.

The MIC2045-1BTS is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC2045-1BTS is determined by strict equivalence across the following critical parameters:

• Output configuration: High Side, N-Channel, 1:1 ratio
• Maximum output current: 6A
• Load voltage range: 0.8V ~ 5.5V
• Supply voltage range: 1.6V ~ 5.5V
• On-state resistance (Rds On): 20mOhm typical
• Interface type: On/Off, Non-Inverting
• Integrated features: Power Good, Slew Rate Controlled, Status Flag
• Fault protection suite: Current Limiting (Adjustable), Open Load Detect, Over Temperature, Reverse Current, UVLO
• Operating temperature range: -40°C ~ 85°C
• Package: 16-TSSOP form factor

The MIC2045-1YTS meets all substitution criteria as a direct equivalent part from the same manufacturer and base product family (MIC2045).

Parameter Comparison

Engineering Selection Recommendations

The MIC2045-1YTS is the direct substitute for the discontinued MIC2045-1BTS. Both parts are functionally identical across all electrical and mechanical parameters. The primary distinction is product status and regulatory compliance:

The MIC2045-1BTS is discontinued and carries RoHS non-compliant status. The MIC2045-1YTS is currently active in production and meets ROHS3 compliance requirements. For new designs or ongoing production requiring regulatory compliance with modern environmental standards, the MIC2045-1YTS is the appropriate selection. The packaging difference (Bulk versus Tube) reflects distribution format only and does not affect component functionality or performance.

Frequently Asked Questions (FAQ)

Q: Are MIC2045-1BTS and MIC2045-1YTS electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including output current rating (6A), on-state resistance (20mOhm typical), voltage ranges, and fault protection features. They are pin-compatible and functionally equivalent.

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

A: Bulk and Tube refer to distribution packaging only. Bulk packaging typically indicates loose components or alternative packaging formats, while Tube packaging contains components in a protective tube. The actual component specifications and performance are identical.

Q: Why is the MIC2045-1BTS discontinued?

A: The MIC2045-1BTS is listed as discontinued at DiGi Electronics. The MIC2045-1YTS remains in active production as the current equivalent offering from Microchip Technology.

Q: Does RoHS compliance affect component performance?

A: RoHS compliance relates to material composition and environmental standards, not electrical performance. Both parts function identically in circuit applications. ROHS3 compliance of the MIC2045-1YTS indicates adherence to current environmental regulations.

Q: Can I use MIC2045-1YTS as a direct replacement in existing designs using MIC2045-1BTS?

A: Yes. The MIC2045-1YTS is a direct substitute with identical pin configuration, package dimensions (16-TSSOP, 0.173" width), and electrical characteristics. No circuit modifications are required.

Q: Are there any inventory or lead time considerations?

A: The MIC2045-1BTS has 10,980 pieces in stock but is discontinued. The MIC2045-1YTS has 2,042 pieces in stock and is actively produced. For ongoing supply assurance, the MIC2045-1YTS is the recommended selection.
