DESCRIPTION
The TPS2590 device provides highly integrated hot-
swap power management and superior protection in
applications where the load is powered by busses up
to 20 V. The maximum UV turn-on threshold of 2.9 V
makes the TPS2590 device well suited to standard
bus voltages as low as 3.3 V. This device is intended
for systems where a voltage bus must be protected to
prevent load shorts from interrupting or damaging
other system components. The TPS2590 device is in
a 16-pin QFN package.
The TPS2590 device has multiple programmable
protection features. Load protection is accomplished
by a non-current-limiting fault threshold, a hard
current-limit threshold, and a fault timer. The dual
current thresholds allow the system to draw high
current for short periods without causing a voltage
droop at the load. An example of this is a disk drive
startup. This technique is ideal for loads that
experience brief high demand, but benefit from
protection levels consistent with average current
draw.
Hotswap MOSFET protection is provided by power
limit circuitry which protects the internal MOSFET
against SOA related failures.
The TPS2590 device provides a fault indicator output
and allows latch off or retry on fault.
