MIC58P01BWM Equivalent & Substitute Parts

Part Overview

The MIC58P01BWM is a Power Switch/Driver IC manufactured by Microchip Technology, designed for latched driver applications with 1:1 bipolar output configuration. This 24-SOIC surface mount device delivers 500mA maximum output current and supports 15V maximum load voltage, making it suitable for power management and switching applications requiring low-side bipolar output control.

The MIC58P01BWM is currently discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this power driver architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MIC58P01BWM is determined by strict equivalence across the following critical parameters:

• Base Product Number: MIC58P01 (identical silicon die and functional architecture)
• Switch Type: Latched Driver (functional operation mode)
• Number of Outputs: 8 (output channel count)
• Ratio - Input:Output: 1:1 (signal-to-output relationship)
• Output Configuration: Low Side (switching topology)
• Output Type: Bipolar (output stage architecture)
• Interface: Strobe, Parallel (control signal protocol)
• Voltage - Load (Max): 15V (maximum rated load voltage)
• Current - Output (Max): 500mA (output current capability)
• Fault Protection: Over Temperature, UVLO (protection features)
• Operating Temperature Range: -55°C ~ 125°C (thermal operating envelope)
• Package / Case: 24-SOIC (0.295", 7.50mm Width) (physical and electrical footprint)

Substitute parts must maintain identical electrical specifications and mechanical compatibility across all listed parameters. Packaging format (Bulk vs. Tube) and compliance certifications may differ without affecting functional substitution.

Parameter Comparison

Engineering Selection Recommendations

The MIC58P01YWM is a direct functional equivalent to the MIC58P01BWM. Both devices share identical electrical specifications, output architecture, and 24-SOIC package footprint, enabling pin-for-pin and functional substitution without circuit modification.

Product Status Consideration: The MIC58P01BWM is discontinued at DiGi Electronics, while the MIC58P01YWM maintains active product status with higher inventory availability (1444 units vs. 728 units). For new designs or ongoing production requiring sustained supply, the MIC58P01YWM is the recommended selection.

Compliance Differentiation: The MIC58P01YWM is ROHS3 compliant with MSL 2 (1 Year), whereas the MIC58P01BWM is RoHS non-compliant with MSL 1 (Unlimited). Applications subject to RoHS regulatory requirements must use the MIC58P01YWM. For legacy systems or applications without RoHS mandates, either part satisfies functional requirements.

Packaging Format: The MIC58P01BWM is supplied in Bulk packaging, while the MIC58P01YWM is supplied in Tube packaging. Packaging format does not affect electrical or mechanical compatibility and is determined by procurement and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the MIC58P01YWM directly replace the MIC58P01BWM in existing designs?

A: Yes. The MIC58P01YWM is a direct functional equivalent with identical electrical specifications, output configuration, and 24-SOIC package footprint. No circuit modifications or PCB redesign are required for substitution.

Q: What are the key parameters that define substitution compatibility for the MIC58P01 series?

A: Substitution compatibility is determined by matching the base product number (MIC58P01), switch type (Latched Driver), output count (8), input:output ratio (1:1), output configuration (Low Side), output type (Bipolar), interface protocol (Strobe, Parallel), maximum load voltage (15V), maximum output current (500mA), fault protection features (Over Temperature, UVLO), operating temperature range (-55°C ~ 125°C), and 24-SOIC package footprint.

Q: Does the difference in RoHS compliance affect functional performance?

A: No. RoHS compliance status reflects manufacturing process and material composition but does not alter electrical performance or functional operation. Selection between RoHS-compliant and non-compliant variants is determined by regulatory requirements applicable to the end application.

Q: What is the significance of the MSL (Moisture Sensitivity Level) difference?

A: MSL rating indicates moisture sensitivity during storage and handling. The MIC58P01BWM (MSL 1) has unlimited shelf life, while the MIC58P01YWM (MSL 2) requires controlled storage conditions for one year. For applications with extended storage periods or high-humidity environments, MSL rating may influence inventory management and handling procedures but does not affect in-circuit performance.

Q: Are there any electrical parameter differences between the two parts?

A: No. Both the MIC58P01BWM and MIC58P01YWM share identical electrical specifications including voltage ratings, current capacity, fault protection features, and operating temperature range. Differences are limited to product status, compliance certifications, packaging format, and moisture sensitivity classification.

Q: What inventory considerations should guide part selection?

A: The MIC58P01YWM offers significantly higher inventory availability (1444 units vs. 728 units) and maintains active product status. For applications requiring sustained supply or rapid procurement, the MIC58P01YWM is the preferred selection. The MIC58P01BWM, while currently in stock, is discontinued and subject to depletion without replenishment.
