MIC5021YN

Overview

The MIC5021YN is a high-side MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 4V to 36V and supports frequencies up to 100kHz, including PWM duty cycles from 2% to 100%. The device features non-inverting logic inputs with defined thresholds of 0.8V for low and 2V for high states. It provides an output drive current of 6mA with typical rise and fall times of 400ns. Packaged in an 8-pin PDIP format, it functions as a buffer or inverter-based MOSFET driver suitable for industrial applications.

Feature Summary

• Designed specifically for high-side MOSFET driving applications
• Supports high-frequency operation up to 100kHz with variable PWM duty cycles
• Features non-inverting input logic compatible with standard digital signals

Applications

• Industrial motor control systems
• High-side switching circuits
• Power management modules requiring isolated gate drive

Procurement Notes

Verify the component marking matches MIC5021YN exactly. Confirm the package type is 8-pin PDIP. Check RoHS compliance status if required by specific project standards. Ensure the operating temperature range meets the application's environmental requirements. Cross-reference the manufacturer date code to ensure availability and authenticity.

Selection Notes

Select this component when a dedicated high-side driver is required for MOSFETs. It is suitable for applications needing reliable switching at frequencies up to 100kHz. Consider the 6mA output current capability against the gate charge requirements of the target MOSFET. The wide supply voltage range allows flexibility in system design.

Part Context

This part belongs to the MIC502x series of gate drivers from Microchip Technology. These devices are engineered for robust performance in noisy industrial environments. The series typically offers solutions for both high-side and low-side driving needs, providing designers with standardized options for power stage control.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family. Verify that any substitute maintains the 36V maximum rating and 100kHz frequency limit. Ensure the replacement also supports the required non-inverting logic configuration.
