Overview
The MIC4423ZWM-TR is a dual low-side MOSFET driver from the MIC4423/4424/4425 family, manufactured by Microchip Technology. It features a BiCMOS/DMOS process for high reliability and robust performance in demanding electrical environments. The device provides a nominal output peak current of 3A and operates within a supply voltage range of 4.5V to 18V. It utilizes a 16-pin SOIC package with lead-free construction. Key timing parameters include typical rise and fall times of 28ns and 32ns, respectively. The component supports inverting input logic and is designed to withstand up to 5V of noise spiking on the ground pin without latch-up or damage.
Feature Summary
- High-output current capability of 3A peak for reliable MOSFET switching
- Robust design resistant to latch-up under all power and voltage ratings
- Immunity to up to 5V noise spiking on the ground pin
- BiCMOS/DMOS process technology for enhanced durability
Applications
- Low-side MOSFET gate driving in power conversion circuits
- Industrial motor control systems requiring high current drive
- Automotive electronics operating in electrically noisy environments
Procurement Notes
Verify the specific suffix ZWMTR corresponds to the 16-pin SOIC tape-and-reel packaging configuration. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the inverting logic configuration matches the system requirements, distinguishing it from non-inverting variants like the MIC4424 series. Cross-reference the MSL rating for proper handling during assembly.
Selection Notes
Select this component when a dual low-side driver with 3A peak current is required. The inverting input type distinguishes it from the MIC4424 (non-inverting) and MIC4425 (mixed). Consider the 16-pin SOIC package size for PCB layout constraints. Verify that the 4.5V to 18V supply range aligns with the target application's voltage levels. The high noise immunity makes it suitable for harsh industrial or automotive settings.
Part Context
This part belongs to the MIC4423/4424/4425 family, which are higher output current versions of the MIC4426/4427/4428 series. These drivers are improved versions of the earlier MIC426/427/428 families. All three families share pin compatibility, facilitating design upgrades. The MIC4423 specifically offers inverting logic, while the MIC4424 provides non-inverting logic, and the MIC4425 combines both functions in a single package.
Replacement Considerations
MIC4424ZWM-TR: Non-inverting logic variant with identical pinout and current specs. MIC4425ZWM-TR: Mixed inverting/non-inverting logic variant. MIC4423ZWM: Tube-packaged version of the same device. MIC4426ZWM-TR: Lower current predecessor, pin-compatible but reduced performance.
