The TPS2070 and TPS2071 provide a complete USB

hub power solution by incorporating four major

functions: current-limited power switches for four

ports, a 3.3-V 100-mA regulator, a 5-V regulator

controller for self-power, and a DP0 line control to

signal attach/detach of the hub.

These devices are designed to meet bus-powered

and self-powered hub requirements. These devices

are also designed for hybrid hub implementations and

allow for automatic switching from self-powered mode

to bus-powered mode if loss of self-power is

experienced (can be disabled by applying a logic high

to BP_DIS).

(1) Pin 12 is active-low ( BPMODE) for

TSS2070 and active-high (BPMODE) for

TPS2071.

TPS2070 TPS2071 www.ti.com SLVS287B – SEPTEMBER 2000 – REVISED SEPTEMBER 2007 3.3V_OUT The internal 3.3-V LDO output can be used to supply up to 100 mA of current to low-power functions, such as hub controllers. VEXT VEXT is used to generate a 5-V source for the SP input by using the internal LDO controller and an external N-channel MOSFET. This pin connects to a 6-V to 9-V power supply and to the drain of the MOSFET if the external LDO is needed.

TPS2070 TPS2071 www.ti.com SLVS287B – SEPTEMBER 2000 – REVISED SEPTEMBER 2007 APPLICATION INFORMATION EXTERNAL CAPACITOR REQUIREMENTS A 0.1-μF ceramic bypass capacitor and a 10-μF bulk capacitor between BP and AGND, close to the device, are recommended. Similarly, a 0.1-μF ceramic and a 68-μF bulk capacitor, from SP to AGND, and from VEXT to AGND if an external 5-V LDO is required, are recommended because of much higher current in the self-powered mode.

TPS2070 TPS2071 www.ti.com SLVS287B – SEPTEMBER 2000 – REVISED SEPTEMBER 2007 POWER DISSIPATION AND JUNCTION TEMPERATURE The major source of power dissipation for the TPS2070 and TPS2071 comes from the internal voltage regulator and the N-channel MOSFETs. Checking the power dissipation and junction temperature is always a good design practice. Begin by determining the rDS(on) of the N-channel MOSFET according to the input voltage and operating temperature.

TPS2070 TPS2071 www.ti.com SLVS287B – SEPTEMBER 2000 – REVISED SEPTEMBER 2007 SELF-POWER TO BUS-POWER OR BUS-POWER TO SELF-POWER TRANSITION An autoswitching function between bus-powered mode and self-powered mode is a feature of the TPS2070 and TPS2071. When this feature is enabled (BP_DIS is inactive) and SP is removed or applied, a transition is initiated. The transition sequence begins with the internal LDO being turned off and its external capacitance discharged.
