MIC4427YN

Overview

The MIC4427YN is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 4.5 V to 18 V and supports CMOS and TTL logic inputs. The device provides a peak output current of 1.5 A with non-inverting configuration. Key timing parameters include rise and fall times of 20 ns and 29 ns, respectively, and maximum on/off delays of 40 ns. It functions in temperatures from -40°C to +85°C and is housed in an 8-pin PDIP package.

Feature Summary

• Dual channel architecture for independent low-side switching control
• Compatible with standard CMOS and TTL logic families
• Non-inverting signal path for direct input-to-output transmission

Applications

• Low-side MOSFET switching in power conversion circuits
• Industrial motor drive control systems
• General purpose power management applications requiring isolated or buffered gate signals

Procurement Notes

Verify the specific suffix 'YN' corresponds to the PDIP-8 through-hole package variant. Confirm RoHS compliance status via official datasheets as regulatory requirements vary by region. Ensure the ordering code matches the required lead time and moisture sensitivity level specifications provided in the manufacturer's documentation.

Selection Notes

Select this component when dual low-side driving capability is required with moderate speed performance. The 1.5 A output current suits small to medium power MOSFETs. Verify that the 4.5 V minimum supply voltage aligns with the system logic levels. Consider the PDIP-8 package constraints if PCB space allows for through-hole mounting.

Part Context

Part of the MIC4427 series, which includes variants like MIC4427YM (SOIC) and MIC4427Y. This family focuses on efficient low-side driving with fast switching characteristics. The MIC4427YN specifically addresses applications needing robust through-hole integration for industrial or prototyping environments.

Replacement Considerations

MIC4427YM serves as a surface-mount equivalent within the same series. MIC4427Y represents the generic part number without package specification. Cross-reference pinouts and electrical limits before substitution.
