The TPS25923x family of eFuses is a highly integrated circuit protection and power management solution 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. 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.

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 TPS25923x output and the gate driven by BFET to prevent current flow from load to source.

TPS259230-41EVM — TPS25923/4/7、簡單 5V/12V eFuse 保護開關評估模組

TPS259230-41EVM 是 TPS25923/4 系列 eFuse 的功能展示，也能以 TPS25970 和 TPS259271 取代 TPS259230 和 TPS259241，藉此評估 TPS259270/1 裝置。  這些 eFuse 是採用超小型封裝的高度積體電路保護開關和電源管理解決方案。這些裝置只使用少量外部元件，並提供多重保護模式。這可針對過載、短路、電壓突波及湧浪電流過大提供穩固的防護。電流限制等級可透過單一外部電阻器設定，且電流限制設定的典型準確度為 ±18%。過電壓事件受內部箝位電路限制在安全的固定最大值，無須外部元件。TPS25924x 裝置可為 12V (...)
