DESCRIPTION
The TPS2140/41/50/51 is a USB 1.0 and 2.0
Specification-compatible IC containing a dual-current-
limiting power switch and an adjustable low dropout
regulator (LDO). Both the switch and LDO limit inrush
current by controlling the turnon slew rate. The unique
dual-current-limiting feature of the switch allows USB
peripherals to utilize high-value capacitance at the
output of the switch, while keeping the inrush current
low. During turnon, the switch limits the current
delivered to the capacitive load to less than 100 mA.
When the output voltage from the switch reaches about
93% of the input voltage, the switch power good output
goes high, and the switch current limit increases to
800mA (minimum), at which point higher current loads
can be turned on. The higher current limit provides short
circuit protection while allowing the peripheral to draw
maximum current from the USB bus.
The switch and LDO function independently, providing
flexibility in DSP applications requiring separate core
and I/O voltages. For example, in a DSP application
operating from a 3.3-V rail, the LDO can supply the DSP
core voltage down to 0.9 V, while the switch powers the
3.3-V (typical) DSP I/O supply. If supply sequencing is
required, the LDO power good output can be used to
enable the switch.
