NCP5111PG

Overview

The NCP5111PG is a half-bridge peripheral driver manufactured by onsemi, housed in an 8-pin PDIP package. It operates with a gate drive supply range of 10 V to 20 V and supports high voltage ranges up to 600 V. The device features independent high-side and low-side outputs with non-inverting logic compatibility for 3.3 V and 5 V inputs. Key electrical parameters include a maximum operating temperature of 125°C and a minimum of -40°C. Propagation delays are characterized by turn-on times of 1.17 µs and turn-off times of 0.17 µs.

Feature Summary

• High dV/dt immunity capability for robust operation in high-voltage environments
• Integrated internal fixed dead time to prevent shoot-through conditions
• Extended allowable negative bridge pin voltage swing for flexible circuit design
• Matched propagation delays between both channels for precise timing control

Applications

• MOSFET and IGBT gate driving in power conversion circuits
• Half-bridge topologies requiring isolated or floating drive signals
• Industrial motor control systems utilizing high-side switching
• AC-DC and DC-DC power supply designs

Procurement Notes

Verify the specific suffix PG indicates the PDIP-8 through-hole package configuration distinct from surface-mount variants. Confirm RoHS compliance status as active and lead-free. Ensure the ordering part number matches the required package style for your PCB assembly process. Cross-reference datasheet revision dates to confirm parameter consistency.

Selection Notes

Select this component when a through-hole half-bridge driver is required for prototyping or low-volume production. The PDIP-8 package facilitates manual soldering and breadboard testing. Consider the 10 V to 20 V supply range and 600 V high-voltage tolerance when designing the gate drive loop. Verify input logic levels match the control system's output voltage standards.

Part Context

This device belongs to the NCP5111 series of high-voltage MOSFET and IGBT drivers. It shares functional similarities with other members like the NCP5111DR2G but differs in packaging. The series is designed for applications demanding reliable switching of power semiconductors with built-in protection features such as fixed dead time.

Replacement Considerations

NCP5111DR2G serves as a direct functional substitute with identical electrical characteristics, differing only in the SOIC-8 surface-mount package format.
