MIC4422BM TR

Overview

The MIC4422BM-TR is a high-speed, low-side single MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 9 A for both sourcing and sinking. The device utilizes an 8-SOIC surface-mount package with a width of 3.90 mm. It features non-inverting logic configuration with typical rise and fall times of 20 ns and 24 ns, respectively. The component supports an operating junction temperature range from -40°C to +150°C and includes internal shoot-through protection.

Procurement Notes

Verify the specific suffix 'BM' against the official Microchip datasheet to confirm the exact temperature grade and package variant. Ensure the 'TR' designation matches the required reel packaging quantity. Cross-reference the manufacturer part number with the latest revision history to avoid obsolete stock. Confirm RoHS compliance status directly from the product documentation before integration.

Selection Notes

Select this component when a single-channel low-side driver with high peak current capability is required. The 9 A output strength suits medium-power applications where faster switching speeds are necessary to reduce conduction losses. The wide operating temperature range makes it suitable for industrial environments. Consider the SOIC-8 footprint constraints during PCB layout planning.
