Description
General part information
TPS2421-2 Series
The TPS2421 device provides highly integrated hot swap power management and superior protection in applications where the load is powered by busses up to 20 V. 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 fault timer is running, 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 in-line with their average current draw.
Hotswap MOSFET protection is provided by power limit circuitry which protects the internal MOSFET against SOA related failures.
