可调瞬态过流消隐计时器；
完备的保护功能：可调输入欠压锁定、可调输入过压锁定、输出快速短路保护、过温保护；
可调输出软起斜率；
负载电流监测；
工作状态指示：
- SGM2536Px版本：可调阈值（PGTH）的电源正常（PG）指示
- SGM2536Fx版本：供电正常（SPGD）指示和故障（nFAULT）指示
SGM2536核心特点
1.SGM2536支持高达23V输入电压，可调节的输出软起斜率可有效减小浪涌电流，保护下游大电流敏感器件并抑制输入端电压波动。
2. SGM2536具有23.7mΩ低导通电阻，可显著降低在大电流应用场景下的损耗，提高系统效率。
3. SGM2536内部集成输入过压锁定，可以在2.5μs内快速响应输入过压事件并切断输出，有效保护下游电压敏感型器件。
4. SGM2536通过外部限流电阻RILIM实现0.5A至6A的可调限流，限流精度可达±10%（典型值，IILIM＞1A）。外部计时电容（CITIMER）实现瞬态过流消隐时间可调，有效增强系统对瞬态过流事件的鲁棒性。当负载电流超过限流阈值IILIM但小于短路阈值（2×IILIM）时，消隐计时器开始计时。若消隐计时器到时之前过流事件被移除，芯片不会触发过流保护；反之，芯片将进入过流保护状态。此外，SGM2536还可通过ILIM引脚电压实现负载电流监测。
5. SGM2536配备了输出快速短路保护（Fast-Trip）功能。当负载电流超过短路电流阈值（2×IILIM）时，SGM2536在500ns内快速切断短路电流，有效保护下游器件。当输出长时间过载或短路时，芯片触发过温保护。自恢复版本（SGM2536xR）触发过温保护后进入重启序列并在故障事件移除后恢复正常工作；锁存版本（SGM2536xL）在触发过温保护后锁死，需要通过输入电源或EN的重置信号方可重启。
6. SGM2536配备多种版本的状态指示。SGM2536Fx版本芯片提供供电正常（SPGD）指示和故障（nFAULT）指示；SGM2536Px版本芯片提供可调阈值（PGTH）可调节的电源正常（PG）指示。
SGM2536应用案例
在消费终端使用OTG功能或反向无线充电功能的场景中，功率需要双向流动。SGM2536搭配电池充电芯片SGM41511可以满足智能手机使用OTG功能的场景，具体应用电路框图如下图所示。
图 2 SGM2536 反向供电应用电路
其中，外部电阻和二极管用于OUT端（电池端）向芯片IN端（USB接口端）供电。检测到有外部组件接入USB后，MCU通过EN信号开启SGM2536内部FETs，提供从OUT到IN的充电路径；OTG功能被禁用时，MCU通过EN信号关闭SGM2536，关断从OUT到IN的充电路径。
