NCP5109ADR2G

Overview

The NCP5109ADR2G is a high-voltage half-bridge gate driver manufactured by onsemi, designed for driving IGBTs and MOSFETs. It features two drivers with dual outputs and delivers an output current of 500 mA. The device operates within a supply voltage range of -300 mV to 20 V and utilizes CMOS logic. Key timing parameters include rise and fall times of 85 ns and 35 ns, respectively, with maximum open and close delay times of 170 ns. It supports shutdown functionality and functions reliably at temperatures up to +150 C in an SOIC-8 surface-mount package.

• Capable of sourcing and sinking 500 mA to drive power devices effectively
• CMOS logic input compatibility ensures straightforward interface with control circuits
• Shutdown pin provides reliable control over driver output states

Applications

• Industrial motor drives
• Power factor correction circuits
• High-frequency DC-DC converters

Procurement Notes

Verify the specific suffix 'ADR2G' against official onsemi documentation to confirm tape-and-reel packaging and lead-free status. Ensure the component meets RoHS requirements for your target market. Cross-reference the datasheet revision date to validate electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when a robust half-bridge solution with moderate drive strength is required. The 500 mA output current suits standard IGBT and MOSFET applications without excessive thermal stress. Verify that the SOIC-8 package fits the PCB layout constraints and that the operating temperature range aligns with the system environment.

Part Context

This part belongs to the NCP5109 series of high-voltage gate drivers from onsemi. It shares architectural similarities with other members like the NCP5104 but may differ in specific electrical characteristics or packaging options. The series is engineered for industrial and consumer power management applications requiring reliable high-side and low-side switching.

Replacement Considerations

Check for direct substitutes such as the NCP5104DR2G within the same family. Confirm pinout compatibility and electrical parameter alignment before substitution. Verify that any alternative maintains the required half-bridge configuration and drive current capabilities.
