Hot-selling and scarce TPS2590RSAR 5-A, 20-V High-Current Load Switch 16QFN spot stock

Product Descriptions

The TPS2590 device provides highly integrated hotswap power management and superior protection inapplications where the load is powered by busses upto 20 V . The maximum UV turn-on threshold of 2.9 Vmakes the TPS2590 device well  suited to standardbus voltages as low as 3.3 V . This device is intendedfor systems where a voltage bus must be protected toprevent  load shorts from interrupting or damagingother system components . The TPS2590 device is ina 16-pin QFN package .

The TPS2590 device has multiple programmableprotection features . Load protection is accomplishedby a non-current-limiting fault   threshold,   a hardcurrent-limit  threshold,  and a fault  timer .  The dualcurrent  thresholds allow the system to draw highcurrent for short  periods without  causing a voltagedroop at the load . An example of this is a disk drivestartup .   This technique is ideal    for  loads thatexperience brief   high demand,   but   benefit   fromprotection levels consistent  with average currentdraw .

Hotswap MOSFET protection is provided by powerlimit  circuitry which protects the internal   MOSFETagainst SOA related failures .

The TPS2590 device provides a fault indicator outputand allows latch off or retry on fault .
