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.
