TC4467EPD Low-Side Gate Driver IC

Part Overview

The TC4467EPD is an active low-side gate driver IC manufactured by Microchip Technology, designed for driving N-Channel and P-Channel MOSFETs in power management applications. This inverting gate driver operates across a supply voltage range of 4.5V to 18V and delivers peak output currents of 1.2A for both source and sink configurations. The device is housed in a 14-PDIP through-hole package and maintains active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required for design flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC4467EPD is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Driven configuration: Low-Side
• Number of drivers: 4
• Gate type: N-Channel, P-Channel MOSFET support
• Supply voltage range: 4.5V ~ 18V
• Logic voltage thresholds: VIL 0.8V, VIH 2.4V
• Peak output current: 1.2A source and sink
• Input type: Inverting

Mechanical Compatibility Requirements:

• Package type: 14-DIP (0.300", 7.62mm)
• Mounting type: Through Hole

Compliance Requirements:

• RoHS3 compliance
• Active product status

The MIC4467ZN qualifies as a direct substitute based on matching all electrical parameters, identical package specifications, and equivalent compliance certifications. Minor variations in rise/fall time (14ns/13ns versus 15ns/15ns) and operating temperature range do not affect substitution eligibility within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Both TC4467EPD and MIC4467ZN are active products from Microchip Technology with full RoHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts is based on application-specific operating temperature requirements and supply chain availability.

The TC4467EPD supports an extended junction temperature range of -40°C to 150°C (TJ), making it suitable for high-temperature industrial and automotive applications. The MIC4467ZN operates across 0°C to 70°C (TA), appropriate for standard commercial and consumer applications. Both devices deliver identical electrical performance within their respective operating ranges and are mechanically interchangeable in 14-DIP through-hole PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can MIC4467ZN replace TC4467EPD in all applications?

A: MIC4467ZN is electrically and mechanically equivalent to TC4467EPD. Substitution is valid when the application operating temperature remains within 0°C to 70°C. Applications requiring extended temperature operation below 0°C or above 70°C must use TC4467EPD.

Q: Are there package compatibility concerns when substituting between these parts?

A: No. Both parts use identical 14-DIP (0.300", 7.62mm) through-hole packaging. PCB layouts and footprints require no modification for substitution.

Q: What is the significance of the rise/fall time difference between TC4467EPD and MIC4467ZN?

A: TC4467EPD specifies 15ns rise and fall times, while MIC4467ZN specifies 14ns and 13ns respectively. Both values are within acceptable margins for low-side gate driver applications and do not affect functional substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TC4467EPD and MIC4467ZN are RoHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity). Compliance certifications are equivalent.

Q: What inventory considerations apply to these substitute parts?

A: Both parts are active products with current manufacturing status. Availability may vary by distributor and region. Verify current stock levels and lead times with your component supplier before design finalization.
