TPS259271DRCR

Texas Instruments TPS25927x 18V eFuses

Texas Instruments TPS25927x 18V eFuses are a highly integrated circuit protection and power management solution in a tiny package. These devices use few external components and provide multiple protection modes. They are a robust defense against overloads, shorts circuits, voltage surges, excessive inrush current, and reverse current. The current limit level can be set with a single external resistor. Over voltage events are limited by internal clamping circuits to a safe fixed maximum, with no external components required. Applications with particular voltage ramp requirements can set dV/dT with a single capacitor to ensure proper output ramp rates.

LM5060 High-Side Protection Controllers

Texas Instruments LM5060 High-Side Protection Controllers with Low Quiescent Current offers intelligent control of a high-side N-channel MOSFET during normal on/off transitions and fault conditions. The constant rise time of the output voltage results from the inrush current control. Both an Input UVLO (with hysteresis) and a programmable input OVP are provided, with an enable input offering a remote on or off control. The initial start-up V_GS fault detection delay time, the transition V_DS fault detection delay time, and the continuous over-current V_DS fault detection delay time is programmed from a single capacitor. The MOSFET is latched off until either the enable input, or the UVLO input is toggled low and then high when a detected fault condition persists longer than the allowed fault delay time.

TPS2592xx Circuit Protection eFuses

Texas Instruments TPS2592xx Circuit Protection eFuses are highly integrated circuit protection and power management solutions in a tiny package. The devices use few external components and provide multiple protection modes. They are a robust defense against overloads, shorts circuits, voltage surges, excessive inrush current, and reverse current. Current limit level can be set with a single external resistor and current limit set has a typical accuracy of ±15%. Over voltage events are limited by internal clamping circuits to a safe fixed maximum, with no external components required. In cases with particular voltage ramp requirements, a dV/dT pin is provided that can be programmed with a single capacitor to ensure proper output ramp rates. Many systems, such as SSDs, must not allow holdup capacitance energy to dump back through the FET body diode onto a drooping or shorted input bus. The BFET pin is for such systems. An external NFET can be connected "Back to Back (B2B)" with the TPS2592 output and the gate driven by BFET to prevent current flow from load to source.
