FEATURES
DESCRIPTION
Integrated Pass MOSFET
The TPS2590 provides highly integrated hot-swap
power
management
and
superior
protection
in
3-V to 20-V Bus Operation
applications where the load is powered by voltages
Programmable Fault Timer
between 3.0 V and 20 V. This device is intended for
Programmable Fault Current
systems where a voltage bus must be protected to
Programmable Hard Current Limit
prevent load shorts from interrupting or damaging
other system components. The TPS2590 is in a
Fast Disable
16-pin QFN package.
Thermal Shutdown
The TPS2590 has multiple programmable protection
Load Fault Alert
features. Load protection is accomplished by a
Latching and Auto-retry Operation
non-current limiting fault threshold, a hard current
4-mm x 4-mm QFN
limit threshhold, and a fault timer. The dual current
thresholds allow the system to draw high current for
-40°C to 125°C Junction Temperature Range
short periods without causing a voltage droop at the
UL Listed - File Number E169910
load. An example of this is a disk drive startup. This
technique is ideal for loads that experience brief high
APPLICATIONS
demand, but benefit from protection levels consistent
with average current draw.
RAID Arrays
Telecommunications
Hotswap MOSFET protection is provided by power
Plug-In Circuit Boards
limit circuitry which protects the internal MOSFET
against SOA related failures.
Disk Drive
Notebooks / Netbooks
The TPS2590 provides a fault indicator output and
allows latch off or retry on fault.
