MIC4422AYM-TR

Overview

The MIC4422AYM-TR is a low-side MOSFET gate driver manufactured by Microchip Technology. It features a single-channel non-inverting output configuration housed in an 8-SOIC surface-mount package. The device supports a supply voltage range of 4.5V to 18V and delivers a peak output current of 9A for both sourcing and sinking. Typical rise and fall times are specified at 20ns and 24ns, respectively. Logic input thresholds are defined at 0.8V for VIL and 3V for VIH. The component operates within a junction temperature range of -40°C to 150°C.

Feature Summary

• Provides high-speed switching capabilities with low propagation delays for efficient power management.
• Features a robust push-pull output stage capable of delivering high peak currents to drive MOSFET gates effectively.
• Includes internal circuitry to prevent shoot-through currents during dead-time intervals in bridge configurations.

Applications

• High-frequency DC-DC converter topologies requiring fast switching speeds
• Motor control systems utilizing N-channel MOSFETs
• Industrial power supplies and inverters

Procurement Notes

Verify the specific suffix 'AYM' corresponds to the required operating temperature grade and packaging format. Confirm that the 8-SOIC footprint matches the target PCB layout dimensions. Ensure compatibility with the system's logic voltage levels against the specified input thresholds. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a single-channel low-side driver with high peak current capability is required. The non-inverting logic simplifies control interface design compared to inverting alternatives. Consider the thermal performance of the SOIC package under continuous load conditions. Evaluate the supply voltage range against the available system rails to ensure stable operation across all operating points.
