Microchip Technology, Inc. PMIC - Power Distribution Switches, Load Drivers UCS2113T-2-V/G4

The UCS2113T-2-V/G4 is a dual USB port power switch designed for applications requiring efficient power distribution and current monitoring. It operates within a source voltage range of 2.9V to 5.5V and can deliver up to 3.0A of continuous current per V_BUS port, with a maximum of 3.4A. The device features low on-resistance of 40 mΩ per switch, independent enable pins for each port, and includes fault alert outputs for monitoring. This power switch supports SMBus 2.0/I²C communication, allowing for programmable current limits and self-contained current monitoring without the need for external sense resistors. It offers various protection features, including undervoltage and overvoltage lockout, back-drive protection, and thermal protection. The UCS2113T-2-V/G4 is suitable for both stand-alone and SMBus-controlled applications, with a wide operating temperature range of -40°C to +105°C. It is packaged in a compact 4x4 mm 20-pin QFN format, making it suitable for space-constrained designs.
