NCP5106BPG

Overview

The NCP5106BPG is a high-voltage gate driver IC manufactured by onsemi, designed for driving two N-channel power MOSFETs or IGBTs in a half-bridge configuration. It features a PDIP-8 through-hole package and supports a supply voltage range of 10V to 20V with a maximum bootstrap voltage of 600V. The device provides independent logic inputs and includes internal cross-conduction protection with a fixed dead time. Key electrical parameters include a peak output current of 250mA source and 500mA sink, rise/fall times of 160ns/75ns, and an operating temperature range from -55°C to +150°C.

Feature Summary

• Provides dedicated high-side and low-side outputs for direct drive of N-channel power MOSFETs or IGBTs in half-bridge topologies.
• Integrates internal fixed dead-time control to prevent cross-conduction between the high-side and low-side switches.
• Features dV/dt immunity to maintain stable operation during rapid voltage transitions in high-noise environments.
• Supports standard TTL/CMOS logic input levels for compatibility with various control circuits.

Applications

• High-voltage half-bridge power converters
• Complementary drive converters such as asymmetric half-bridge and active clamp topologies
• Electronic ballast drivers for fluorescent lamps

Procurement Notes

Verify component authenticity and datasheet revision when sourcing this part, as it is listed as obsolete. Confirm that the PDIP-8 package meets your PCB layout requirements. Ensure that the specified operating temperature range aligns with your system's thermal design constraints. Check for RoHS compliance status in the latest manufacturer documentation before finalizing procurement plans.

Selection Notes

Select the NCP5106BPG when a through-hole solution is required for half-bridge applications involving high-voltage MOSFETs or IGBTs. This model is suitable for designs needing robust cross-conduction protection and high dV/dt immunity. Consider alternative surface-mount versions if space constraints preclude the use of the PDIP-8 package. Verify that the 600V bootstrap rating matches the maximum bus voltage of your application.

Part Context

The NCP5106BPG belongs to the NCP5106 series of high-voltage gate drivers from onsemi. This series includes variants like the NCP5106A for independent high-side/low-side configurations and surface-mount options such as the NCP5106BDR2G. The B variant specifically targets half-bridge applications with integrated dead-time control, distinguishing it from the A version which offers independent inputs without fixed dead time.

Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the obsolete status. Surface-mount equivalents like the NCP5106BDR2G offer similar electrical characteristics but require PCB redesign. Evaluate the NCP5106AMNTWG for updated packaging options, noting potential differences in lead time and availability compared to the legacy PDIP-8 component.
