MIC4423CWM TR

Overview

The MIC4423CWM-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. The device features an inverting configuration with rise and fall times of 12 ns, and a maximum propagation delay of 75 ns. It functions at a quiescent current of 2.5 mA and supports CMOS and TTL logic inputs. The component is housed in a 16-pin SOIC package and is rated for operation between 0°C and +70°C.

Feature Summary

• Dual-channel architecture providing independent control for two low-side MOSFETs
• High-speed switching capability with 12 ns rise and fall times
• Inverting logic configuration compatible with standard digital interfaces
• Robust 3 A peak output current drive capability

Applications

• Low-side switching in DC-DC converter topologies
• Motor control circuits requiring dual MOSFET drive
• Power supply management systems utilizing low-side topology

Procurement Notes

Verify the specific suffix against official documentation, as variations exist within the family. Confirm that the TR designation corresponds to the correct reel packaging format required for your assembly process. Ensure compatibility with the intended operating temperature range of 0°C to +70°C before finalizing procurement decisions.

Selection Notes

Select this component when a dual low-side driver with moderate speed (12 ns) is required. It is suitable for applications where inverting logic is acceptable. Compare against non-inverting variants like the MIC4424 if signal phase preservation is necessary. Ensure the 3 A drive current meets the gate charge requirements of the target MOSFETs.

Part Context

This part belongs to the MIC4423/4424/4425 family of high-reliability BiCMOS/DMOS drivers. These devices are pin-compatible with earlier generations like the MIC423/424/425 but offer improved performance and robustness. The MIC4423 specifically provides the inverting function for dual low-side applications.

Replacement Considerations

MIC4424CWM-TR offers identical electrical specifications but with a non-inverting configuration.
