TPS2421-1 具有遇故障重试功能的 3-20V 集成 FET 0-5A 热插拔
TPS2421-1 描述
The TPS2421 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. 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 is an easy to use devices in an 8-pin PowerPad™ SO-8 package.
The TPS2421 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 fault timer is running, without causing a voltage droop at the load
