MIC4467BN

Overview

The MIC4467BN is a low-side MOSFET gate driver from the Microchip Technology MIC4467 series. It features four independent inverting drivers with a peak output current of 1.2 A. The device operates on a supply voltage range of 4.5 V to 18 V and utilizes CMOS logic. Key electrical parameters include rise and fall times of 25 ns, and maximum on/off delay times of 75 ns. It functions within an operating temperature range of 0°C to +70°C and is housed in a 14-pin PDIP package.

Feature Summary

• Integrates four independent low-side drivers for driving power MOSFETs and similar capacitive loads
• Provides high-efficiency, low-impedance drive capability with rail-to-rail voltage swings
• Features fast switching times suitable for heavily loaded clock lines and coaxial cables

Applications

• Driving power MOSFETs in power conversion circuits
• Buffering heavily loaded clock lines
• Driving coaxial cables
• Actuating piezoelectric transducers

Procurement Notes

Verify the specific suffix 'BN' against the manufacturer's official datasheet to confirm the package type (PDIP) and commercial temperature grade. Ensure compatibility with the required input logic levels and supply voltage constraints before procurement. Cross-reference the part number with authorized distributors to confirm current availability status.

Selection Notes

Select this component when a quad-channel low-side driver is required for driving multiple MOSFETs simultaneously. It is suitable for applications needing 1.2 A peak current and fast switching speeds. Consider the PDIP package for through-hole mounting requirements. Verify that the system operates within the specified 0°C to +70°C temperature range.

Part Context

The MIC4467BN belongs to the MIC4467/4468/4469 family of quad 1.2A-peak low-side MOSFET drivers. This family expands upon earlier single- and dual-output designs by integrating four high-power drivers into a single package, which improves system reliability and reduces total system cost compared to using multiple discrete drivers.
