3 Description
The TPS249x are easy-to-use, positive high voltage,
10-pin Hot Swap Power Manager devices that safely
drive an external N-channel MOSFET switch. The
power limit and current limit (both are adjustable and
independent of each other) ensure that the external
MOSFET operates inside a selected safe operating
area (SOA) under the harshest operating conditions.
Applications include inrush current limiting, electronic
circuit breaker protection, controlled load turn-on,
interfacing to down-stream DC-to-DC converters, and
power feed protection. These devices are available in
a small, space-saving 10-pin VSSOP package and
significantly reduce the number of external devices,
saving precious board space. The TPS249x is
supported by application notes, an evaluation
module, and a design tool.
