NCP4413DR2

Overview

The NCP4413DR2G is a high-speed half-bridge gate driver manufactured by onsemi. It features a peak output current of 2 A and operates within a supply voltage range of 4.5 V to 18 V. The device supports PWM frequencies up to 1 MHz and includes adjustable dead-time control with a minimum delay of 60 ns. Key protection mechanisms include under-voltage lockout (UVLO) for both the supply and bootstrap voltages, as well as shoot-through prevention. It is housed in a compact SOIC-8 surface-mount package.

Feature Summary

• Integrated adjustable dead-time control to prevent cross-conduction in half-bridge configurations
• High-speed switching capability supporting PWM frequencies up to 1 MHz
• Dual under-voltage lockout protection for supply and bootstrap circuits
• Robust 2 A peak sink/source output current drive

Applications

• Motor control systems requiring precise half-bridge driving
• DC-DC converter topologies utilizing synchronous rectification
• Industrial power supplies and inverters
• Battery management systems with isolated gate drive requirements

Procurement Notes

Verify the complete part number suffix, typically 'DR2G', to ensure compliance with RoHS standards and specific tape-and-reel packaging quantities. Confirm that the procurement source provides official datasheets matching the onsemi specification sheet. Check for any recent product change notifications regarding pinout or electrical characteristics before finalizing orders.

Selection Notes

Select this component when designing circuits requiring independent adjustment of rise and fall times to optimize electromagnetic interference. Ensure the external bootstrap capacitor and diode selection aligns with the 1 MHz operating frequency. Verify that the PCB layout supports the thermal requirements of the SOIC-8 package under continuous load conditions.

Part Context

This device belongs to the NCP4413 family of half-bridge drivers designed for high-frequency applications. It complements other onsemi power management solutions by providing reliable gate drive isolation and protection. The series is commonly integrated into motor drives and power conversion modules where efficiency and switching speed are critical performance factors.

Replacement Considerations

Direct substitutes may include the NCP4412 or NCP4414 variants, which offer similar functionality but with different dead-time adjustment ranges or output current capabilities. Cross-reference pinouts and electrical specifications carefully to ensure compatibility with existing board layouts and thermal designs.
