Overview
The NCP4423DWR2 is a dual high-speed MOSFET driver manufactured by onsemi. It provides independent high-current drive capability with a peak output current of 3A for both the high-side and low-side channels. The device operates within a supply voltage range of 4.5V to 18V. It features adjustable rise and fall times to minimize electromagnetic interference (EMI). The component is housed in a 16-lead SOIC Wide package.
Feature Summary
- Dual-channel architecture providing independent control for high-side and low-side MOSFETs
- High-speed switching performance with adjustable transition times to reduce EMI
- Integrated protection mechanisms including under-voltage lockout and shoot-through prevention
Applications
- Motor control systems requiring precise gate driving
- Industrial power supplies and inverters
- Battery management systems
Procurement Notes
Verify the specific suffix DWR2 against the manufacturer's latest datasheet to confirm pinout compatibility and thermal characteristics. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the part number with official onsemi distribution channels to avoid counterfeit components. Confirm that the packaging type matches the required reel or tube specifications for automated assembly processes.
Selection Notes
Select this component when a dual-channel driver with moderate 3A peak current is sufficient for the application. It is suitable for designs where adjustable slew rates are necessary to balance switching speed and EMI constraints. Consider the 16-lead SOIC package for PCB layout requirements. Evaluate the operating temperature range to ensure it meets the environmental conditions of the target system.
Part Context
This device belongs to the NCP442x series of high-speed MOSFET drivers from onsemi. The series includes variants with different current capabilities, such as the 9A NCP4420. The NCP4423DWR2 specifically targets applications needing balanced performance between drive strength and electromagnetic compatibility without the higher cost or complexity of isolated drivers.
Replacement Considerations
Direct replacements include other models within the NCP442x family, such as the NCP4422, provided the current rating and pinout compatibility are verified. Check for equivalent parts from other manufacturers offering dual high-speed MOSFET drivers with similar 3A output currents and SOIC-16 packages.
