说明

TPS2295x-Q1 是具有受控导通功能的小型单通道负载开关。此类器件包含一个可在 0.7V 至 5.7V 输入电压范围内运行的 N 沟道 MOSFET,并且可支持高达 5A 的连续电流。

该器件具有可调欠压锁定 (UVLO) 和可调电源正常 (PG) 阈值,可提供电压监控和可靠的电源时序功能。该器件的可调上升时间控制可大大降低各种大容量负载电容的浪涌电流,从而降低或消除电源压降。开关由可与低压控制信号直接连接的开关输入 (EN) 单独控制。该器件集成了一个 15Ω 片上负载,以便在禁用开关时使输出快速放电。增强型快速输出放电 (QOD) 功能可在器件断电后的短时间内继续有效,以便使输出完成放电。

TPS2295x-Q1 采用小型、节省空间的 10-SON 封装,此类封装具有集成散热焊盘,可实现高功率耗散。该器件在自然通风环境下的额定运行温度范围为 –40°C 至 +125°C。
