P9147NRGI8

Full Half-Bridge (H Bridge) Drivers Overview

The P9147NRGI8 is a distributed power unit (DPU) designed as an additional phase for the P9145 PMIC. It operates within a 5.6V to 12.6V input voltage range and delivers up to 6A peak output current per device. The component features a 2.0MHz switching frequency with internal PWM generation, supporting automatic phase-shedding, PFM, and LDO modes. It utilizes a simple two-wire interface for configuration and control by the host PMIC. Packaged in a 12-lead 3mm x 4mm DFN, it functions over an industrial temperature range of -40°C to +85°C.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

This component is officially listed as obsolete. Verification of end-of-life status is required before integration. No new production units are available from the manufacturer. Designers must confirm availability through secondary market channels or initiate immediate redesign processes using approved replacement components to ensure long-term supply chain stability.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component only when integrating with the Renesas P9145 PMIC ecosystem. It is specifically engineered for high-voltage applications like 12V ATX systems rather than single 5V supplies. Ensure the design supports the proprietary two-wire interface for proper communication and control between the host PMIC and the DPU.
