TPS2590 3V 至 20V 大电流负载开关

TPS2590 描述

The TPS2590 provides highly integrated hot-swap power management and superior protection in applications where the load is powered by voltages between 3.0 V and 20 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 is in a 16-pin QFN package. The TPS2590 has multiple programmable protection features. Load protection is accomplished by a non-current limiting fault threshold, a hard current limit threshhold, 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.
