Introduction
TPS2553-Q1 配电开关采用 N 沟道 MOSFET，适用于需要精确限流或存在高容性负载及短路的应用场合，可提供高达 1.5A 的持续负载电流。这些器件通过一个外部电阻器，提供 75mA 至 1.7A（典型值）间的可编程电流限制阈值。在较高电流限制设置下，电流限制精度可达 ±6%。对电源开关的上升和下降时序进行控制，以大幅降低接通/切断期间的电流冲击。
当输出负载超过限流阈值时，TPS2553-Q1 器件进入恒定电流模式，将输出电流限制在安全水平。当输出电压被驱动至高于输入电压时，内部反向电压比较器将禁用电源开关，以保护开关输入端上的器件。在过流和反向电压情况下，FAULT 输出被拉低。
The TPS2553-Q1 is a current-limited power-distribution switch using N-channel MOSFETs for applications where short circuits or heavy capacitive loads will be encountered, providing up to 1.5 A of continuous load current. These devices allow the user to program the current-limit threshold between 75 mA and 1.7 A (typ) via an external resistor. Additional device shutdown features include overtemperature protection and reverse-voltage protection. The device incorporates an internal charge pump and gate drive circuitry necessary to drive the N-channel MOSFET. The charge pump supplies power to the driver circuit and provides the necessary voltage to pull the gate of the MOSFET above the source. The charge pump operates from input voltages as low as 2.5 V and requires little supply current. The driver controls the gate voltage of the power switch. The driver incorporates circuitry that controls the rise and fall times of the output voltage to limit large current and voltage surges and provides built-in soft-start functionality. The TPS2553-Q1 enters constant-current mode when the load exceeds the current-limit threshold.
