Product details

What the 155 µA supply current buys the BOM

The TPS2514DBVR draws 155 µA from the USB VBUS rail when active — low enough that a battery-powered host can leave the charging port enabled without draining the main battery overnight. For a 5000 mAh power bank, that quiescent draw extends standby months beyond a discrete-switch solution.

The SOT-23-6 package is a standard TI footprint with broad second-source availability from multiple distributors.

The small footprint suits compact USB port designs where board space is at a premium.

Frequently asked questions

What is the output current limit of TPS2514DBVR?

The TPS2514DBVR is a USB DCP controller and power switch; the output current limit is set by the internal current-sense and regulation loop to comply with USB Battery Charging Specification 1.2. The exact limit value is specified in the datasheet — the part negotiates the charging profile so the attached device draws its rated current.

Does TPS2514DBVR support USB BC 1.2?

Yes — the TPS2514DBVR is designed for USB Dedicated Charging Port (DCP) applications and implements the handshake required by USB Battery Charging Specification 1.2. It presents the correct divider voltages on D+ and D- to signal a dedicated charger to the downstream device.

What is the closest functional second-source — TPS2514ADBVR?

The primary difference is a 200 µA supply current vs. the TPS2514DBVR's 155 µA. For most charging port designs the delta is negligible, but if quiescent current is critical, the TPS2514DBVR is the lower-Iq option.
