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 简易 5V/12V 电子保险丝保护开关评估模块

TPS259230-41EVM 可用于演示 TPS25923/4 系列电子保险丝的功能，还可在 TPS25970 和 TPS259271 替换 TPS259230 和 TPS259241 后，用于评估 TPS259270/1 器件。  这些电子保险丝是采用超小型封装的高度集成电路保护开关和电源管理解决方案。这些器件使用很少的外部组件，但可提供多种保护模式。它们能够有效地防止过载、短路、电压浪涌和过高的浪涌电流。电流限制水平可通过单个外部电阻器进行设置，且电流限值的典型设定精度可达 ±18%。过压事件受内部钳位电路的限制，保持在一个安全的固定最大值内，无需外部元件。TPS25924x 器件为 (...)
