Hello, Welcome to Dasenic

The TPS2061 is an ideal power distribution switch that is designed to operate with 2.7V to 5.5V supply voltages. It includes features like over-current protection, thermal shutdown, and an active low enable pin for controlling operation. This makes it useful for applications that require controlled power distribution to multiple sub-circuits. Functions - Power Switching: Allows the control of power to various loads with minimal on-resistance. - Current Limiting: Protects the load and power supply from excessive current draw. - Thermal Shutdown: Shuts down the switch if the chip overheats, providing additional protection. - Active Low Enable Control: The device can be activated or deactivated using a low voltage signal. Applications - USB Power Distribution: Provides power switching between multiple USB devices. - Portable Devices: Used in battery-powered devices requiring efficient power management. - Consumer Electronics: Equipment such as cameras, media players, and smartphones. - Industrial Use: Utilized in industrial controls and other applications where load switching is required. Alternative Parts - TPS2060: A slightly different version with comparable features. - TPS2051: Another power distribution switch with higher current capabilities. - TPS2113: A power multiplexer switch that can be used in power distribution applications. Embedded Modules Modules containing the TPS2061 will likely include evaluation modules or development kits that help in prototyping and testing applications. These can facilitate quick design iterations and testing scenarios involving the TPS2061. Related Q&A Q1: What is the voltage range for the TPS2061DR? A1: The TPS2061DR operates with a supply voltage range of 2.7V to 5.5V. Q2: How does the current limiting feature work in the TPS2061? A2: The TPS2061 features a built-in current limiting function that helps prevent excessive current from flowing through the switch, thereby protecting both the load and the power supply. Q3: Can the TPS2061 be used in USB applications? A3: Yes, it is commonly used in USB power distribution applications where controlled power switching is necessary. Q4: What happens during a thermal shutdown in the TPS2061? A4: If the internal temperature of the TPS2061 exceeds safe limits, the thermal shutdown mechanism will turn off the switch to prevent damage to the device. Q5: Are there any development kits available for the TPS2061? A5: Yes, Texas Instruments offers evaluation modules and development kits that include the TPS2061, which are useful for prototyping and testing applications.
