3-V To 20-V High-Current Load Switch

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. 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 provides a fault indicator output and allows latch off or retry on fault. By Texas Instruments
