DescriptionThe TPS2421 device provides highly integrated hot
swap power management and superior protectionin
applications where the loadis poweredby bussesup 20 V. The TPS2421 deviceis well suited to
standard bus voltagesas lowas 3.3V becauseof the
maximum-UV turnon threshold of 2.9 V. These
devices are very effectivein systems wherea 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 protectionis accomplisheda non-current limiting fault threshold,a hard
current limit, anda fault timer. The current dual
thresholds allow the system to draw short high
current pulses, while the fault timeris running, without
causinga voltage droopat the load. An exampleof
thisisa disk drive startup. This techniqueis ideal for
loads that experience brief high demand, but benefit
from protection levels in-line with their average
current draw.
Hotswap MOSFET protectionis provided by power
limit circuitry which protects the internal MOSFET
against SOA related failures.
The TPS2421 deviceis availablein latch-off on fault
(TPS2421-1) and retryon fault (TPS2421-2).
