Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC4422ABN is determined by strict equivalence across the following critical parameters:

• Driven configuration: Low-side operation
• Channel configuration: Single channel
• Gate type: N-channel MOSFET driver
• Supply voltage range: 4.5V ~ 18V
• Logic voltage thresholds: VIL 0.8V, VIH 3V
• Peak output current: 9A source and sink
• Input logic: Non-inverting
• Switching characteristics: Rise/fall times 20ns/24ns
• Operating temperature range: -40°C ~ 150°C
• Package type: 8-DIP through-hole
• Pinout compatibility: Identical pin configuration

The MIC4422AYN qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MIC4422AYN is the direct substitute for the MIC4422ABN. Both devices are manufactured by Microchip Technology and share identical electrical and mechanical specifications, including supply voltage range, output current capability, switching characteristics, and package configuration.

The MIC4422AYN offers two significant advantages over the obsolete MIC4422ABN:

• Product status: Active production ensures long-term availability and supply chain continuity
• Compliance: ROHS3 compliant versus RoHS non-compliant, meeting current environmental and regulatory requirements

For new designs or component replacement in existing applications, the MIC4422AYN is the appropriate selection. Pin-for-pin compatibility and identical functional performance ensure direct substitution without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the MIC4422AYN directly replace the MIC4422ABN in existing designs?

A: Yes. The MIC4422AYN is a direct pin-for-pin and functional equivalent. All electrical parameters, including supply voltage, output current, switching times, and operating temperature range, are identical. No circuit modifications are required.

Q: What is the difference between the MIC4422ABN and MIC4422AYN?

A: The primary differences are product status and compliance certification. The MIC4422ABN is obsolete, while the MIC4422AYN is in active production. The MIC4422AYN is ROHS3 compliant, whereas the MIC4422ABN is RoHS non-compliant. All functional and electrical specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both devices use the 8-DIP (0.300", 7.62mm) through-hole package with identical pinout and mechanical dimensions. PCB layout and footprints are interchangeable.

Q: Why is the MIC4422ABN obsolete?

A: The MIC4422ABN has been discontinued by Microchip Technology. The MIC4422AYN represents the current production equivalent and is the recommended replacement for supply chain continuity.

Q: Does the ROHS3 compliance of the MIC4422AYN affect compatibility?

A: No. ROHS3 compliance indicates improved environmental and regulatory adherence. The MIC4422AYN is fully compatible with applications designed for the MIC4422ABN and offers enhanced compliance status for modern manufacturing and environmental standards.
