The TPS2421 device is well suited to standard bus voltages as low as 3.3 V because of the maximum-UV turnon threshold of 2.9 V. These devices are very effective in systems where a voltage bus must be protected to prevent shorts from interrupting or damaging the unit. The TPS2421 device is an easy to use devices in an 8-pin PowerPad™ SO-8 package. The TPS2421 device has multiple programmable protection features. Load protection is accomplished by a non-current limiting fault threshold, a hard current limit, and a fault timer. The current dual thresholds allow the system to draw short high current pulses, while the faul...
