MIC4467ZN

Overview

The MIC4467ZN is a low-side MOSFET gate driver manufactured by Microchip Technology. It features four independent inverting drivers in a 14-pin PDIP package. The device operates with a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 1.2 A. Key electrical parameters include a rise time of 25 ns, fall time of 25 ns, and maximum turn-on/off delay times of 75 ns. It functions within an operating temperature range of 0°C to +70°C and consumes 200 µA of operating supply current.

Feature Summary

• Provides four independent low-side gate drive channels for power switching applications.
• Features latch-up protection to ensure robust operation under transient conditions.
• Supports input signals referenced up to -5V relative to the driver ground.
• Capable of driving capacitive loads such as MOSFET gates with fast transition times.

Applications

• Low-side switching control for N-channel power MOSFETs
• Industrial motor drive circuits requiring isolated or referenced gate signals
• Power supply topologies utilizing low-side synchronous rectification

Procurement Notes

Verify the specific suffix 'ZN' corresponds to the PDIP-14 through-hole package variant. Confirm RoHS compliance status via the manufacturer's latest documentation. Ensure the ordering quantity aligns with the standard tube packaging configuration provided by the distributor. Cross-reference the datasheet revision date to verify parameter accuracy against your design requirements.

Selection Notes

Select this component when four independent low-side drivers are required in a single package. The inverting logic configuration must match the control signal polarity needs of the system. Consider the 1.2 A peak current capability for driving moderate-capacitance MOSFETs. The PDIP-14 package is suitable for prototyping or applications where surface-mount space is not constrained.

Part Context

The MIC4467ZN belongs to the MIC446x series of Power Logic CMOS quad drivers from Microchip Technology. This series includes variants with different logical configurations, such as non-inverting options like the MIC4469. These devices are designed for general-purpose power management and motor control applications requiring reliable gate drive performance.

Replacement Considerations

The MIC4469ZN is a functional substitute offering both inverting and non-inverting outputs in the same package. Verify pin compatibility and logical inversion requirements before substitution. Other members of the MIC446x family may share similar electrical characteristics but differ in channel configuration.
