NCP51152BADR2G

Isolators - Gate Drivers Overview

The NCP51152BADR2G is an isolated single-channel gate driver from onsemi, housed in an 8-SOIC package. It provides a 3.75 kVRMS isolation rating and supports split outputs for independent control of high-side and low-side drive currents. The device delivers peak source and sink currents of 4.5 A and 9 A, respectively. It operates with a supply voltage range of 3 V to 20 V and features TTL-compatible logic inputs. Key timing parameters include a maximum propagation delay of 55 ns, a rise time of 12 ns, and a fall time of 8.3 ns. The component functions within a temperature range of -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

• Provides 3.75 kVRMS reinforced isolation via capacitive coupling technology.
• Features split output architecture allowing independent optimization of turn-on and turn-off speeds.
• Supports both inverting and non-inverting input configurations for flexible system integration.

Isolators - Gate Drivers Applications

• Driving power MOSFETs in isolated DC-DC converter topologies
• Gate driving for IGBTs in industrial motor drives
• Isolated interfaces in solar microinverter systems

Isolators - Gate Drivers Procurement Notes

Verify the specific ordering suffix DR2G to confirm tape-and-reel packaging configuration. Ensure the B suffix is accounted for if specific thermal or mechanical variants are required by the design. Cross-reference the manufacturer datasheet for RoHS compliance status and moisture sensitivity level before finalizing procurement plans.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching with asymmetric drive strength is required. The split output capability allows designers to optimize efficiency by slowing down turn-on to reduce EMI while maintaining fast turn-off. Verify that the application voltage does not exceed the 20 V supply limit and that the isolation requirements align with the 3.75 kVRMS rating.

Isolators - Gate Drivers Part Context

This part belongs to the NCP51152 series of isolated gate drivers. It is distinct from half-bridge drivers like the NCP5111 due to its single-channel topology. The device is designed to replace discrete isolation solutions, offering a compact SOIC-8 footprint suitable for space-constrained power electronics designs requiring galvanic isolation.

Isolators - Gate Drivers Replacement Considerations

Check for direct pin-to-pin replacements within the same family, such as other variants of the NCP51152 series. Verify that any substitute maintains the 3.75 kVRMS isolation rating and compatible current drive capabilities.
