BD2320UEFJ-LAE2

Gate Driver Overview

The BD2320UEFJ-LAE2 is a dual-channel isolated gate driver manufactured by ROHM Semiconductor, designed for high-side and low-side switching applications. It operates within a supply voltage range of 7.5 V to 14.5 V and supports a high-side floating supply voltage up to 100 V. The device delivers a minimum peak output current of 3500 mA during turn-on and 4500 mA during turn-off. Typical switching times are 27 ns for turn-on and 29 ns for turn-off, with an offset supply leakage current maximum of 10 μA. It is housed in an HTSOP-J8 package measuring 4.9x6.0 mm with a thickness of 1.0 mm, suitable for surface mount installation across an operating temperature range of -40°C to 125°C.

Gate Driver Feature Summary

• Provides non-inverting drive signals for both high-side and low-side power switches.
• Supports high-voltage floating operation with a 100 V VB rating for high-side control.
• Features fast switching characteristics with typical rise and fall times under 30 ns.
• Includes built-in protection against excessive offset supply leakage current.

Gate Driver Applications

• Industrial motor drives requiring isolated gate control
• Inverter circuits for AC/DC and DC/AC conversion
• High-frequency switching power supplies

Gate Driver Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as manufacturing lines may change while maintaining identical electrical specifications. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure that the design accommodates the HTSOP-J8 footprint dimensions and thermal characteristics specified in the official datasheet to guarantee reliable performance under operational conditions.

Gate Driver Selection Notes

Select this component when a dual-channel isolated driver is required for driving IGBTs or MOSFETs in high-voltage environments. The 100 V floating supply capability makes it suitable for half-bridge configurations. Consider the 3.5 A source and 4.5 A sink currents to ensure adequate drive strength for the target power devices. Verify that the operating temperature range aligns with the environmental constraints of the final application.

Gate Driver Part Context

This part belongs to the BD2320 series of isolated gate drivers from ROHM Semiconductor. It serves as a recommended replacement for the BD2320EFJ-LA, which is not recommended for new designs. Both parts share the same pinout, package type, and electrical specifications, ensuring drop-in compatibility for existing designs transitioning to newer production lines.

Gate Driver Replacement Considerations

The BD2320EFJ-LA is a direct substitute with identical pinout and package. Both parts share the same electrical characteristics and HTSOP-J8 form factor, allowing for seamless integration without circuit redesign.
