The TPS2584x-Q1 is a USB Type-A BC1.2 charging solution that includes a synchronous DC/DC converter. With cable droop compensation, the Vbus voltage remains constant regardless of load current, ensuring connected portable devices charge at optimal current and voltage even under heavy loads.
The TPS2584x-Q1 includes high bandwidth analog switches for DP and DM pass-through.
The TPS25840-Q1 also integrates short-to-battery protection on VBUS, DM_IN and DP_IN pins. These pins can withstand voltage up to 18 V. TPS25842-Q1 does not support data line (Dx) short-to-VBAT protection.
The synchronous buck regulator operates with current mode control and is internally compensated to simplify design. A resistor on the RT pin sets the switching frequency between 300 kHz and 2.2 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 TPS2584x-Q1 integrates electrical signatures necessary for legacy devices which use USB data lines to determine charging configuration.
A precision current sense amplifier is included for user programmable cable droop compensation and current limit tuning. 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 VBUS voltage measured at a connected portable device remains approximately constant, regardless of load current, allowing the portable devices battery charger to work optimally.
The USB specifications require current limiting of USB charging ports, but give system designers reasonable flexibility to choose overcurrent protection levels based on system requirements. The TPS2584x-Q1 uses a novel two-threshold current limit circuit allowing system designers to either program average current limit protection of the buck regulator, or optionally, current limit using an external NMOS between the CSN/OUT and BUS pins. The NFET implementation enables the TPS2584x-Q1 buck regulator to supply a 5-V output for other loads during an overcurrent condition on the USB port.
Protection features include cycle-by-cycle current limit, hiccup short-circuit protection, undervoltage lockout, VBUS overvoltage and overcurrent, data line (Dx) short to VBUS, and die overtemperature protection.
The TPS25840-Q1 includes high bandwidth analog switches for DP and DM pass-through, and support data line (Dx) short to VBAT protection. TPS25842-Q1 dont support data line (Dx) short to VBAT protection.
