高电平有效且具有反向阻断功能的 0.275-2.7A 可调节ILIMIT、2.5-5.5V、70mΩ USB 电源开关

TPS25221 旨在用于可能会遇到大电容负载和短路事件的 应用 。可编程电流限制阈值可通过一个外部电阻器设定在 275mA 至 2.7A（典型值）之间。在更高电流限制设置上可实现严格至 ±6% 的 ILIMIT 精度。通过控制电源开关的上升时间和下降时间，可最大限度地降低开通和关断期间的电流浪涌。 \n\n当负载尝试吸收超过编程的 ILIMIT 的电流时，内部 FET 会进入恒定电流模式，以确保 ILOAD 等于或低于 ILIMIT。在固有的抗尖峰脉冲时间之后，FAULT 输出将会在过流状态期间维持低电平。 • 2.5V 至 5.5V VOPERATING\n• 与 TPS2553 引脚对引脚兼容\n• 2A ICONT_MAX \n• 0.275A 至 1.7A 可调节 ILIMIT（2.7A 时精确度为 ±6.5%）\n• 70mΩ（典型值）RON \n• 1.5µs 短路响应\n• 8ms 故障报告抗尖峰脉冲\n• 反向电流阻断（禁用时） \n• 内置软启动\n• UL 60950 和 UL 62368 认证\n• 15kV ESD 保护，符合 IEC 61000-4-2 标准（带外部电容）;
