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
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
