Integrated Pass MOSFET  
3.3-V to 20-V Bus Operation  
Programmable Fault Current  
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.

Latch-Off on Fault (-1) and Retry (-2) Versions  
SO-8 PowerPad™ 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. 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.

RAID Arrays  
Telecommunications  
Plug-In Circuit Boards  
Disk Drive  
Hotswap MOSFET protection is provided by power  
limit circuitry which protects the internal MOSFET  
against SOA related failures.  
The TPS2421 is available in latch-off on fault (-1) and  
retry on fault (-2).
