FEATURES
DESCRIPTION
The TPS25910 device provides highly integrated hot-
• Up to 20-V Bus Operation
swap power management and superior protection in
• Integrated 30-mΩ Pass MOSFET
applications up to 20 V. The maximum UV turn-on
• Programmable Current Limit from:
threshold of 2.9 V makes the TPS25910 device well
0.83 A to 6.5 A
suited to standard bus voltages as low as 3.3 V. This
device is intended for systems where a voltage bus
• Programmable Inrush Current Slew Rate
must be protected from undesired permanent and
• Thermal Shutdown and fault alert
transient overload.
• 4-mm x 4-mm QFN16
At start-up or when hot plugging into the system bus,
• –40°C to 125°C Junction Temperature Range
the TPS25910 device limits the inrush current by
