TPS2149 TPS2159
SLVS401 AUGUST 2001
3.3-V LDO AND DUAL SWITCH FOR USB BUS-POWERED HUB POWER MANAGEMENT
FEATURES DESCRIPTION
The TPS2149 incorporates two power distribution switches and an LDO in one small package, providing a USB bus-powered hub power management solution that saves up to 60% in board space over typical implementations. The TPS2149 meets USB 2.0 bus-powered hub requirements. An integrated LDO regulates the 5-V bus power down to 3.3 V for the USB controller. The two MOSFET switches provide power to the downstream ports. With independent enables, the downstream ports remain unpowered until the hub completes enumeration. Each power-distribution switch is capable of supplying 200 mA of continuous current, and the independent logic enables are compatible with 5-V logic and 3-V logic. The switches and the LDO are designed with controlled rise times and fall times to minimize current surges. The TPS2149 has active-low enables while the TPS2159 has active-high enables.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltages are with respect to GND.
