TPS202x/3x and TPS204x/5x Power Distribution Switches
Texas Instruments offers a variety of power switch devices for USB applications:
the TPS202x, TPS203x, TPS204x, and the TPS205x. All devices are high-side
switches with built-in overcurrent protection that includes open-drain, active-low
overcurrent flag output for overcurrent reporting. The switches provide power
switching and maintenance-free fault protection; they are controlled by 3.3-V and
5-V logic level compatible enables. For added flexibility in interfacing with hub
controllers, the devices are available in active-low or active-high enables.
The TPS202x (active-low) and TPS203x (active-high) families of devices are
50-m
high-side N-channel MOSFET switches that are offered at different
current limit levels. The TPS202x/3x families are ideal for ganged-port protected
power distribution system topologies.
The TPS2041/2/4 and TPS2051/2/4 series of devices are 135-m
high-side
N-channel MOSFET switches rated for a fixed continuous current of 0.5 A with
typical current limit of 0.9 A. The TPS204X series differs in the number of power
switches available in each packaged device: TPS2041 (Single), TPS2042 (Dual),
TPS2044 (Quad). The TPS2041 series is ideal for individual port protection of
one-port (TPS2041), two-port (TPS2042), or four-port (TPS2044) topologies.
The TPS204X devices are enabled with an active-low 3-V or 5-V logic enable.
The TPS2042 and TPS2044 devices incorporate a dual thermal trip to allow fully
independent operation of the dual power distribution switches. In over-current or
short-circuit conditions, the junction temperature rises. Once the die temperature
rises to an internal set trip point, the thermal sense circuitry determines which
switch is in an over-current condition and turns that power switch off, isolating the
fault without interrupting operation of the adjacent power switch. The second
thermal trip point is a higher temperature point that turns off both switches.
Active-high versions are also available: TPS2051, TPS2052, and TPS2054 as
single, dual, and quad power switches. Table 1 lists characteristics of the
TPS20xx family of devices.
