USB Sort-C Energy Financial institution Reference Design

The facility financial institution reference design helps 2-4 cell configurations and options Twin Function Energy performance for versatile functions.

The reference design from Renesas introduces a USB-certified single-port energy financial institution optimized to be used with lithium-ion batteries. It helps configurations of two to 4 cells in sequence, with a default setting of three cells. Moreover, it incorporates a battery monitor perform on the board, enhancing efficiency monitoring and security.

The facility financial institution incorporates a USB Sort-C port with Twin Function Energy (DRP) performance. This enables the port to help each sink mode for charging the ability financial institution and supply mode for delivering energy to exterior gadgets. The supply mode may also help a programmable energy provide (PPS), making it versatile for numerous functions.

For personalisation, the ability financial institution comes with commonplace firmware that may be adjusted by altering the board settings to accommodate configurations of two, 3, or 4 cells. This flexibility is efficacious for tailoring the ability financial institution’s efficiency to particular wants.

The USB certification consists of two configurations underneath Technical ID (TID) numbers: 1090007, RTK-251-1PowerBank3, which permits the machine to deal with 100W in sink mode and 45W in supply mode, and 1090008, RTK-251-1PowerBank3, which helps 100W in sink mode and 15W with PPS in supply mode.

A firmware technology help software is supplied. This GUI software allows customers to change USB PD protocol parameters, providing extra management over the machine’s performance and efficiency. This complete toolset ensures that builders can simply customise and optimize the ability financial institution for numerous functions, enhancing its versatility and value.

This USB Energy Supply system incorporates a single USB-Sort-C port with a twin function functionality, supporting Strive.SRC mode for versatile energy interplay. The facility supply can output commonplace voltages of 5, 9, 12, 15, and 20V, including as much as two further voltages and supporting programmable energy provide (PPS) at 5V and 5VProg. It will probably additionally sink energy from 5 to 20V with variable enter. It’s distinctive to the mannequin RTK0EUG011D06010BJ and features a USB-Sort-C Authentication Responder and a USB Energy Supply Firmware Replace function (PDFU). The battery charger is designed for Li-ion batteries, accommodating configurations of two, 3, or 4 sequence cells, with a default setting of three cells. Extra options embrace trickle charging, 5 LED indicators for battery and USB port standing, and safety mechanisms for over temperature on the USB-Sort-C receptacle, over-voltage on VBUS voltage, and present on VBUS present, guaranteeing secure and dependable operation.
