DescriptionThe TPS2421 device provides highly integrated hot swap power management and superiorprotection in applications where the load is powered by busses up to 20 V. The TPS2421 device iswell suited to standard bus voltages as low as 3.3 V because of the maximum-UV turnon threshold of2.9 V. These devices are very effective in systems where a voltage bus must be protected to preventshorts from interrupting or damaging the unit. The TPS2421 device is an easy to use devices in an8-pin PowerPad? SO-8 package.
The TPS2421 device has multiple programmable protection features. Load protection isaccomplished 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 faulttimer is running, without causing a voltage droop at the load. An example of this is a disk drivestartup. This technique is ideal for loads that experience brief high demand, but benefit fromprotection levels in-line with their average current draw.
Hotswap MOSFET protection is provided by power limit circuitry which protects theinternal MOSFET against SOA related failures.
The TPS2421 device is available in latch-off on fault (TPS2421-1) and retry on fault(TPS2421-2).
