The devices use few • Fixed 15-V Over Voltage Clamp external components and provide multiple protection modes. They are a robust defense against overloads, • 1-A to 5-A Adjustable ILIMIT shorts circuits, voltage surges, excessive inrush • ±8% ILIMIT Accuracy at 3.7A current, and reverse current. • Reverse Current Blocking Support Current limit level can be set with a single external • Programmable OUT Slew Rate, UVLO resistor. Over voltage events are limited by internal • Built-in Thermal Shutdown clamping circuits to a safe fixed maximum, with no external components required. • UL 2367 Recognition Pending • Safe During Single Point Failure Test (UL60950) Applications with particular voltage ramp requirements can set dV/dT with a single capacitor to • Small Foot Print – 10L (3 mm x 3 mm) VSON ensure proper output ramp rates. Many systems, such as SSDs, must not allow holdup capacitance 2 Applications energy to dump back through the FET body diode • Adapter Powered Devices onto a drooping or shorted input bus. The BFET pin is for such systems. An external NFET can be • HDD and SSD Drives connected “Back to Back (B2B)” with the TPS25924x • Set Top Boxes output and the gate driven by BFET to prevent • Servers / AUX Supplies current flow from load to source (see Figure 43). • Fan Control Device Information(1) • PCI/PCIe Cards PART NUMBER PACKAGE BODY SIZE (NOM) TPS259241 VSON (10) 3.00 mm × 3.00 mm TPS259240 (1) For all available packages, see the orderable addendum at the end of the data sheet.
