MIC4422CM-TR Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The MIC4422CM-TR is a low-side gate driver IC manufactured by Microchip Technology, designed for driving IGBT and N-Channel MOSFET gates in power management applications. This non-inverting single-channel driver operates from a 4.5V to 18V supply and delivers 9A peak output current in both source and sink configurations.

The MIC4422CM-TR 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 applications utilizing this gate driver topology.

Substitute Part Grouping Explanation

Substitution of the MIC4422CM-TR is determined by strict equivalence across the following critical parameters:

Driven Configuration: Low-side operation only
Channel Count: Single channel
Gate Type Compatibility: IGBT and N-Channel MOSFET support
Supply Voltage Range: 4.5V ~ 18V
Logic Input Levels: VIL 0.8V, VIH 2.4V
Peak Output Current: 9A source and sink capability
Input Logic: Non-inverting
Switching Performance: Rise/fall times of 20ns/24ns
Temperature Range: 0°C ~ 150°C junction temperature
Package: 8-SOIC surface mount form factor

The MIC4422ZM-TR meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is product status and compliance certification, not functional or electrical performance.

Engineering Selection Recommendations

The MIC4422ZM-TR is the direct substitute for the MIC4422CM-TR. Both parts share identical electrical specifications, switching characteristics, and package geometry. The MIC4422ZM-TR is currently in active production status with 5200 units available in inventory, compared to the discontinued MIC4422CM-TR.

The MIC4422ZM-TR carries ROHS3 compliance certification, whereas the MIC4422CM-TR is RoHS non-compliant. For applications subject to RoHS regulatory requirements or customer specifications mandating RoHS compliance, the MIC4422ZM-TR is the appropriate selection. Both parts maintain identical REACH and ECCN classifications.

No functional redesign or circuit modification is required when transitioning from MIC4422CM-TR to MIC4422ZM-TR. Pin configuration, electrical performance, and thermal characteristics remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can MIC4422ZM-TR replace MIC4422CM-TR in existing designs?

A: Yes. The MIC4422ZM-TR is electrically and mechanically identical to the MIC4422CM-TR. No circuit modifications, PCB layout changes, or firmware updates are necessary. Direct substitution is supported.

Q: What is the difference between MIC4422CM-TR and MIC4422ZM-TR?

A: The primary differences are product status and RoHS compliance. The MIC4422CM-TR is discontinued; the MIC4422ZM-TR is active production. The MIC4422ZM-TR is ROHS3 compliant, while the MIC4422CM-TR is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package with identical pinout and footprint. PCB designs require no modification.

Q: What supply voltage range does this gate driver support?

A: Both the MIC4422CM-TR and MIC4422ZM-TR operate from 4.5V to 18V supply voltage. Logic input levels are VIL 0.8V and VIH 2.4V.

Q: What is the peak output current capability?

A: Both parts deliver 9A peak output current in source and sink configurations, suitable for driving IGBT and N-Channel MOSFET gates with fast switching transitions.

Q: What switching speed does this gate driver provide?

A: Typical rise and fall times are 20ns and 24ns respectively, enabling fast gate switching for power management applications requiring rapid MOSFET or IGBT turn-on and turn-off transitions.

Q: Is this a single-channel or multi-channel gate driver?

A: This is a single-channel, low-side gate driver. It is designed for driving one gate per IC. Multi-channel applications require multiple ICs or alternative multi-channel gate driver products.
