MIC4424ZWM-TR

Overview

The MIC4424ZWM-TR 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 delivers a peak output current of 3 A for both sourcing and sinking. The device features non-inverting inputs and is housed in a 16-SOIC surface-mount package with a width of 7.50 mm. Typical rise and fall times are 28 ns and 32 ns, respectively, with a maximum propagation delay of 75 ns. It supports CMOS and TTL logic levels, with input thresholds at 0.8 V and 2.4 V. The operating junction temperature range extends from 0°C to 150°C.

• Robust noise immunity capable of surviving ground pin spikes up to 5 V
• Latch-up free operation under all conditions within power and voltage ratings

Applications

• Industrial motor control systems
• Power supply circuits requiring efficient MOSFET switching
• Automotive electronics applications
• Inverter and converter topologies

Procurement Notes

Verify the specific suffix ZWM against the official datasheet to confirm the SOIC-16 package and lead-free status. Confirm RoHS compliance and REACH status as these attributes may vary by manufacturing batch or region. Check for moisture sensitivity level (MSL) requirements if storage conditions are critical. Ensure the ordering part number matches the exact tape and reel specifications required for your assembly line equipment. Cross-reference the manufacturer's latest product change notices for any recent packaging or testing site updates.

Selection Notes

Select this component when high-speed switching of low-side N-channel and P-channel MOSFETs is required. The 3 A drive current ensures fast transition times, reducing switching losses in power stages. The wide operating temperature range makes it suitable for demanding industrial environments. Verify that the input logic levels match the driving microcontroller or FPGA outputs. Consider the 16-SOIC footprint constraints during PCB layout design to ensure adequate thermal dissipation and trace routing for the high-current outputs.

Part Context

This device belongs to the MIC4423/4424/4425 family of BiCMOS/DMOS drivers. These components are pin-compatible with each other and represent an evolution of the earlier MIC426/427/428 series. They offer improved reliability and higher output currents compared to their predecessors. The family is designed to operate reliably in electrically noisy environments without latching issues.
