NCP5104DR2G

Overview

The NCP5104DR2G is a half-bridge gate driver manufactured by onsemi, designed for driving IGBT and N-channel MOSFETs. It operates within a supply voltage range of 10 V to 20 V and supports high-side bootstrap voltages up to 600 V. The device features two drivers with output source/sink currents of 250 mA and 500 mA respectively. Propagation delays are characterized by rise and fall times of 85 ns and 35 ns. It accepts non-inverting logic inputs compatible with 3.3 V and 5 V levels, with an allowable negative bridge pin voltage swing down to -10 V. Operating temperatures span from -40 °C to +125 °C.

Feature Summary

• Supports high-voltage applications with a maximum bootstrap voltage of 600 V
• Features internal fixed dead time to prevent shoot-through in half-bridge configurations
• Provides robust dV/dt immunity for reliable operation in noisy environments
• Compatible with standard 3.3 V and 5 V input logic signals

Applications

• Industrial motor drives
• Power supply circuits
• Inverter systems

Procurement Notes

Verify the specific suffix DR2G corresponds to the SOIC-8 package and tape-and-reel configuration required for your assembly process. Confirm that the automotive-grade AEC-Q100 qualification aligns with your system's reliability standards. Ensure the supplier provides valid RoHS compliance documentation. Cross-reference the manufacturer part number against official datasheets to avoid counterfeit components.

Selection Notes

Select this component when a non-isolated half-bridge driver is needed for high-voltage switching applications. It is suitable for designs requiring moderate drive current capabilities with integrated dead-time control. Consider the SOIC-8 package constraints and thermal performance relative to your PCB layout. Evaluate the 600 V rating against the peak voltage stresses in your specific power stage topology.

Part Context

This part belongs to the NCP5104 series of half-bridge gate drivers. It shares functional similarities with other onsemi drivers like the NCV5104DR2G, which offers automotive qualification. The device is categorized under PMIC gate drivers and is distinct from isolated or single-channel alternatives in the same product family.

Replacement Considerations

The NCV5104DR2G is a verified alternative offering automotive-grade qualification. Check for pin-to-pin compatibility and ensure the replacement meets the required operating temperature and voltage specifications.
