The TPS25910 device provides highly integrated hot-swap power management and superior
protection in applications up to 20 V. The maximum UV turn-on threshold of 2.9 V makes the TPS25910
device well suited to standard bus voltages as low as 3.3 V. This device is intended for systems
where a voltage bus must be protected from undesired permanent and transient overload.
At start-up or when hot plugging into the system bus, the TPS25910 device limits the
inrush current by controlling the ramp rate of the output voltage, VOUT. The
slew rate of VOUT can be adjusted with a capacitor between the GATE pin and
the GND pin.
Built in SOA protection ensures that the internal MOSFET operates inside a safe operating
area (SOA) under the harshest operating conditions. In addition, the current-limit threshold, which
is independent of the power limit, can be adjusted with a resistor between the ILIM pin and the GND
The TPS25910 device provides a fault indicator output when in thermal fault.
The TPS25910 device is available in a 16-pin QFN package.
