MIC94300YCS-TR Equivalent & Substitute Parts

Part Overview

The MIC94300YCS-TR is a Power Switch/Driver IC from Microchip Technology's Ripple Blocker™ series, designed for high-side N-channel switching applications. This component operates as a 1:1 power switch with 200mA output capacity in a compact 4-WLCSP (0.88x0.88mm) package. The product is currently obsolete, making equivalent and substitute parts necessary for new designs or production continuity. Alternative parts must maintain functional compatibility across switching topology, output current rating, voltage specifications, and thermal performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MIC94300YCS-TR is determined by the following critical parameters:

Primary Compatibility Criteria:

• Switch topology: High-side power switch with 1:1 input-to-output ratio
• Output channel type: N-channel or P-channel configurations
• Maximum output current: 200mA minimum requirement
• Load voltage range: 1.8V ~ 3.6V (primary), with tolerance for extended ranges
• Interface: On/Off control with non-inverting input
• Fault protection: Current limiting and over-temperature protection
• Operating temperature range: -40°C to 125°C minimum
• Surface mount packaging in compact BGA or TMLF form factors
• RoHS3 compliance and MSL Level 1 rating

Substitute Categories:

Category 1 - Direct Microchip Equivalent: MIC94300YMT-TR maintains identical electrical specifications and series lineage, differing only in packaging format (4-TMLF vs. 4-WLCSP) and product status (Active vs. Obsolete).

Category 2 - Texas Instruments P-Channel Alternatives: TPS22910AYZVT, TPS22913BYZVT, and TPS22913CYZVT provide higher current capacity (2A) and extended load voltage range (1.4V ~ 5.5V) with P-channel topology. These parts accommodate applications requiring greater current headroom and wider voltage flexibility while maintaining high-side switching configuration and fault protection features.

Parameter Comparison

Engineering Selection Recommendations

MIC94300YMT-TR is the primary equivalent for direct replacement. This part maintains identical electrical specifications, series heritage, and compliance certifications while offering active product status and improved availability. The packaging change from 4-WLCSP to 4-TMLF® requires PCB layout modification but provides superior handling characteristics and manufacturing compatibility.

TPS22910AYZVT, TPS22913BYZVT, and TPS22913CYZVT serve as functional alternatives for applications requiring higher current capacity or extended voltage range. These Texas Instruments parts operate with P-channel topology instead of N-channel, necessitating circuit topology review. The 2A output current rating and 1.4V ~ 5.5V load voltage range accommodate broader application requirements. All three maintain ROHS3 compliance, MSL Level 1 rating, and active product status. Selection between TPS22913BYZVT and TPS22913CYZVT depends on packaging preference (Cut Tape vs. Tape & Reel) and inventory requirements.

Frequently Asked Questions (FAQ)

Q: Can MIC94300YMT-TR directly replace MIC94300YCS-TR without circuit modification?

A: Electrical specifications are identical, enabling functional substitution. However, the package change from 4-WLCSP (0.88x0.88mm) to 4-TMLF® (1.2x1.6mm) requires PCB footprint and layout redesign. Pin assignments and electrical connections remain compatible.

Q: What is the primary difference between the Microchip and Texas Instruments substitute options?

A: MIC94300YMT-TR maintains N-channel topology and 200mA current rating identical to the original part. Texas Instruments alternatives (TPS22910AYZVT, TPS22913BYZVT, TPS22913CYZVT) employ P-channel topology with 2A output current and extended voltage range (1.4V ~ 5.5V vs. 1.8V ~ 3.6V). Circuit topology must be evaluated for P-channel compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MIC94300YMT-TR, TPS22910AYZVT, TPS22913BYZVT, and TPS22913CYZVT all carry ROHS3 Compliant certification and MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What packaging options are available among the substitute parts?

A: MIC94300YMT-TR is supplied in 4-TMLF® (1.2x1.6mm) format. TPS22910AYZVT is available in Tape & Reel packaging. TPS22913BYZVT is supplied in Cut Tape & Digi-Reel® format. TPS22913CYZVT is available in Tape & Reel packaging. All Texas Instruments parts use 4-DSBGA (0.88x0.88mm) package.

Q: How do operating temperature ranges compare?

A: MIC94300YCS-TR and MIC94300YMT-TR operate across -40°C to 125°C (junction temperature). Texas Instruments alternatives operate across -40°C to 85°C (ambient temperature). Applications requiring operation above 85°C ambient require thermal analysis to confirm junction temperature compliance.

Q: What fault protection features differ between substitute options?

A: MIC94300YCS-TR and MIC94300YMT-TR provide current limiting (fixed) and over-temperature protection. TPS22910AYZVT provides reverse current and UVLO (under-voltage lockout) protection. TPS22913BYZVT and TPS22913CYZVT add load discharge capability to the reverse current and UVLO protection set.
