Overview
The MIC4422YN is a low-side MOSFET gate driver manufactured by Microchip Technology. It features a single non-inverting output capable of delivering a peak current of 9 A. The device operates within a supply voltage range of 4.5 V to 18 V and utilizes an 8-pin PDIP package for through-hole mounting. Key timing parameters include a rise time of 20 ns and a fall time of 24 ns. The component supports an operating temperature range from -40°C to 85°C.
Feature Summary
- Provides high peak output current capability for efficient MOSFET switching
- Features a non-inverting logic configuration for direct signal control
- Designed with low internal resistance to minimize power dissipation
Applications
- Power supply circuits requiring low-side switching
- Motor drive systems utilizing MOSFETs
- Inverter topologies for AC-DC conversion
Procurement Notes
Verify the specific suffix 'YN' corresponds to the 8-pin PDIP package when sourcing. Confirm that the required lead-free status aligns with project specifications. Ensure the supplier provides official Microchip documentation to validate the part number against the datasheet. Cross-reference the manufacturer code to avoid confusion with similar Micrel or legacy variants.
Selection Notes
Select this component for applications requiring a single-channel low-side driver with high current capacity. The PDIP package is suitable for prototyping and through-hole designs where surface mount options are not feasible. Consider the 9 A peak current rating to ensure adequate drive strength for the target MOSFET's gate charge requirements at the intended switching frequency.
Part Context
This device belongs to the MIC4422 series of MOSFET drivers, which includes various packaging options such as SOIC and TSSOP. The 'YN' suffix specifically denotes the PDIP variant. Other series members like MIC4422YM offer identical electrical performance but in surface-mount packages. The series is designed for general-purpose high-speed switching applications.
Replacement Considerations
MIC4422YM serves as a pin-compatible alternative in SOIC-8 packaging. MIC4422ZN offers the same functionality in a TSSOP package. Verify that any substitute maintains the 9 A peak current rating and 4.5 V to 18 V supply range.
