●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.
