BQ500511RHAR

Product Overview

The BQ500511RHAR from Texas Instruments is a wireless power transmitter PMIC for surface-mount power-management designs. It uses a 40-VFQFN Exposed Pad package and has the 40-VQFN (6x6) package designation. The device operates from a 2 V to 3.6 V supply and has a supply current of 3.45 mA. Its operating temperature range is -40°C to 85°C. These characteristics define the part as a transmitter-side IC for wireless power transfer applications that must fit within a surface-mount package.

Design & Procurement Notes

When selecting this part, verify that the system supply remains within 2 V to 3.6 V and that the 3.45 mA supply current is compatible with the power budget. Confirm that the expected operating temperature conditions fall within -40°C to 85°C, and account for package and PCB thermal effects around the exposed pad. The 40-VFQFN Exposed Pad format and 40-VQFN (6x6) package designation require a surface-mount footprint, solder paste, reflow profile, and pad layout that match the mechanical and electrical requirements of the board. Check the package drawing and land pattern before finalizing the PCB layout and assembly documentation. The supply range and current value should also be checked against the system power source and any shared rails.
