Description

The TPS2553DBVR load switch has a controlled rise time for reducing inrush current. This feature is beneficial for controlling the initial surge of current when connecting a load to the power supply, thereby preventing voltage drops. Its protection features include a thermal shutdown that disables the device when the junction temperature exceeds the specified threshold, protecting the device from damage due to overheating. The device can be turned on and off through a logic-compatible enable pin, making it easily controllable from a microcontroller or other logic devices.
