The TPS2585x-Q1 is an integrated USB charging port solution which includes a synchronous, high efficiency DC/DC converter and integrated detection and control for implementing USB Battery Charging 1.2 and Type-C ports.

The TPS2585x-Q1 is a highly-integrated USB Type-C charging controller for single-port application.

The device integrates a monolithic, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs and one USB current-limit switch with charging port auto-detection. The TPS2585x-Q1 offers a compact, high efficiency solution with excellent load and line regulation over a wide input supply range. The synchronous buck regulator operates with peak-current mode control and is internally compensated to simplify design. For TPS25854-Q1, a resistor on the FREQ pin sets the switching frequency between 200 kHz and 800 KHz. For TPS25855-Q1, a resistor on the FREQ pin sets the switching frequency between 200 kHz and 3 MHz. Operating below 400 kHz results in better system efficiency. Operation above 2.1 MHz avoids the AM radio bands and allows for use of a smaller inductor.

The TPS2585x-Q1 integrates standard USB Type-C port controller functionality including Configuration Channel (CC) logic for 3-A and 1.5-A current advertisement. Battery Charging (Rev. 1.2) integration provides the required electrical signatures necessary for non-Type-C, legacy USB devices which use USB data line signaling to determine USB port current sourcing capabilities.

The TPS2585x-Q1 supports intelligent thermal regulation. The output current can be regulated according to external TS threshold. Also, the device has integrated VCONN power that can meet USB3.1 power requirement. The part is especially suitable for single port application due to the high system integration and small footprint.

The TPS2585x-Q1 output voltage is fixed at 5.1 V. The device also integrates a precision current sense amplifier for user programmable cable droop compensation and current limit tuning, the maximum cable compensation voltage is limited to 400 mV. Cable compensation aids portable devices in charging at optimum current and voltage under heavy loads by changing the buck regulator output voltage linearly with load current to counteract the voltage drop due to wire resistance in automotive cabling. The BUS voltage measured at a connected portable device remains approximately constant, regardless of load current, allowing the portable device’s battery charger to work optimally.

The TPS2585x-Q1 provides various safety features for USB charging and system operations, including external negative thermistor monitoring, cycle-by-cycle current limit, hiccup short-circuit protection, undervoltage lockout, BUS overcurrent and die overtemperature protection.

The device family is available in a 25-pin, 3.5-mm × 4.5-mm QFN package.
