Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC4468BWM TR is determined by strict equivalence across the following critical parameters:

• Driven configuration (Low-Side)
• Number of independent drivers (4)
• Gate type compatibility (N-Channel, P-Channel MOSFET)
• Supply voltage range (4.5V ~ 18V)
• Logic voltage thresholds (VIL 0.8V, VIH 2.4V)
• Peak output current specifications (1.2A source, 1.2A sink)
• Input signal type (Non-Inverting)
• Switching performance (Rise/Fall time 14ns/13ns)
• Operating temperature range (-40°C ~ 85°C)
• Package form factor (16-SOIC surface mount)

The MIC4468YWM-TR meets all these criteria and is classified as a direct substitute. The primary distinction between these parts is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The MIC4468YWM-TR is the direct substitute for the obsolete MIC4468BWM TR. Both parts share identical electrical and functional specifications across all critical parameters including driver configuration, output current capability, switching performance, and operating conditions.

Selection between these parts should be based on the following factors:

Product availability: The MIC4468YWM-TR is currently in active production status with higher inventory levels (3614 Pcs), whereas the MIC4468BWM TR is obsolete with limited remaining stock (887 Pcs).

Regulatory compliance: The MIC4468YWM-TR meets ROHS3 compliance requirements, while the MIC4468BWM TR is RoHS non-compliant. For applications subject to RoHS regulations, the MIC4468YWM-TR is the required choice.

Packaging format: The MIC4468YWM-TR is supplied in Tape & Reel (TR) configuration, suitable for automated assembly processes. The MIC4468BWM TR is supplied in bulk packaging.

Moisture handling: The MIC4468YWM-TR has an MSL rating of 2 (1 Year), requiring standard moisture control during storage and handling. The MIC4468BWM TR has an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Can the MIC4468YWM-TR be used as a direct replacement for the MIC4468BWM TR?

A: Yes. Both parts are electrically and functionally identical across all specified parameters. The MIC4468YWM-TR is the active production equivalent of the obsolete MIC4468BWM TR and can be used as a direct substitute without circuit modifications.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active), packaging format (bulk vs. Tape & Reel), RoHS compliance status (non-compliant vs. ROHS3 compliant), and moisture sensitivity level (MSL 1 vs. MSL 2). Electrical and functional specifications are identical.

Q: Are there any pin compatibility or package concerns when substituting?

A: No. Both parts use the identical 16-SOIC (0.295", 7.50mm Width) surface mount package with the same pin configuration and footprint. PCB layout and assembly processes require no modification.

Q: What is the supply voltage range for these gate driver ICs?

A: Both the MIC4468BWM TR and MIC4468YWM-TR operate with a supply voltage range of 4.5V to 18V, supporting a wide range of power management applications.

Q: How many independent gate drivers are integrated in this IC?

A: Both parts contain four independent low-side gate drivers, each capable of driving N-Channel and P-Channel MOSFETs with 1.2A peak output current (source and sink).

Q: What is the logic voltage threshold specification?

A: The logic voltage thresholds are VIL = 0.8V and VIH = 2.4V for both parts, defining the input signal levels for proper gate driver operation.

Q: What switching performance can be expected from these devices?

A: Both parts provide typical rise and fall times of 14ns and 13ns respectively, enabling fast switching transitions in power management circuits.

Q: Are there any temperature operating range limitations?

A: Both parts operate across the industrial temperature range of -40°C to 85°C (TA), suitable for standard commercial and industrial applications.
