MIC4420ZN

Overview

The MIC4420ZN is a low-side MOSFET gate driver manufactured by Microchip Technology in an 8-pin PDIP package. It provides a peak output current of 6 A with a non-inverting configuration. The device operates within a supply voltage range of 4.5 V to 18 V and features rise and fall times of 25 ns each. It draws an operating supply current of 450 uA and functions reliably across a temperature range from 0°C to +125°C.

Feature Summary

• Delivers high peak output current for efficient MOSFET switching
• Features fast rise and fall times for reduced switching losses
• Supports wide supply voltage flexibility for diverse design requirements

Applications

• Low-side MOSFET driving in power conversion circuits
• Industrial motor control systems
• High-frequency switching applications requiring fast edge rates

Procurement Notes

Verify the specific suffix 'ZN' corresponds to the 8-pin PDIP tube packaging when ordering. Confirm that the non-inverting logic level matches the control signal source. Ensure the selected component meets the required thermal dissipation capabilities for the intended application environment.

Selection Notes

Select this component when a single-channel, low-side driver with 6 A capability is required. Consider the 8-pin PDIP form factor for through-hole assembly needs. Evaluate the 4.5 V to 18 V supply range against the system's available voltage rails to ensure proper operation without external level shifting.

Part Context

This part belongs to the MIC4420 family of gate drivers, which includes variants such as the MIC4420ZM in SOIC-8 packaging. The family offers buffer or inverter-based MOSFET driving solutions. The ZN suffix specifically denotes the PDIP package type, distinguishing it from surface-mount alternatives within the same functional series.

Replacement Considerations

The MIC4420BMM serves as a pin-compatible alternative in MSOP-8 packaging. Verify that the package footprint change is acceptable for the PCB layout before substitution.
