P9147NRGI

Full Half-Bridge (H Bridge) Drivers Overview

The P9147NRGI8 is a distributed power unit (DPU) designed as an extension 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 or phase. The component utilizes a 2.0MHz switching frequency with internal PWM generation and supports automatic phase-shedding, PFM, and LDO modes. It features a simple 2-wire interface for configuration and status exchange with the host PMIC. The device is housed in a 12-lead 3mm x 4mm DFN package and functions within an industrial temperature range of -40°C to +85°C.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify component obsolescence status prior to design finalization, as this part may be discontinued. Confirm that the host system utilizes the compatible P9145 PMIC for proper interface operation. Ensure layout guidelines are followed to maintain signal integrity on the proprietary control bus. Check for available replacement options if long-term supply stability is required for production.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when the base PMIC requires additional current capacity beyond its native limits. It is suitable for applications needing precise current scaling through digital control rather than analog feedback. Consider parallel configurations if higher total current is necessary. Verify input voltage compatibility with the 5.6V to 12.6V operational window.
