The TPS2051BDBVT is a single-load current-limited power distribution switch integrated circuit (IC) manufactured by Texas Instruments. It is designed to provide efficient power distribution for systems that require tight control of current draw. This IC provides fast over-current protection while maintaining low I2C-compatible control and diagnosis capabilities. The TPS2051BDBVT integrates an adjustable voltage-controlled current source, which allows the user to set a maximum load current limit between 0.1A and 4.5A depending on voltage drop selection. The device also provides additional features such as precision current and voltage measurements, open and short detection, circuit protection and diagnostic capabilities. The TPS2051BDBVT is rated at 45V and is available in a 14-pin TSSOP package.
