Full Half-Bridge (H Bridge) Drivers Procurement Notes

This component is officially classified as obsolete. Support is strictly limited to customers who have already adopted these products. Verify availability through authorized channels, noting that samples may be unavailable and stock status varies. Confirm compatibility with existing system designs before procurement due to the discontinued status.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this module when integrating with Intersil 5V PWM controllers such as the ISL6398 or ISL9585x series. It is suitable for applications requiring reduced external components and minimum PCB real estate. Ensure the design accommodates the 3.5x5mm QFN-24 package dimensions and utilizes the three-state PWM interface for proper control logic.

Full Half-Bridge (H Bridge) Drivers Part Context

The ISL99135BDRZ-T belongs to the ISL99125B/ISL99135B family of DrMOS power modules from Renesas (formerly Intersil). These devices are engineered to create complete voltage regulator solutions by combining drivers and MOSFETs. This specific part offers higher current capability compared to its sibling, the ISL99125B, targeting demanding high-density power applications.
