TPS2041BMDBVTEP

The TPS2041BMDBVTEP from Texas Instruments is an enhanced product power-distribution switch designed to handle heavy capacitive loads and short circuits. It features integrated 70-mΩ N-channel MOSFET power switches, suitable for power-distribution systems requiring multiple switches in a single package.

This device operates within a voltage range of 2.7 V to 5.5 V and provides 500 mA of continuous current. Key protection features include thermal and short-circuit protection, with a current limit accuracy of ±30%. The current limit ranges from a minimum of 0.45 A to a maximum of 1.55 A. It also incorporates undervoltage lockout and a deglitched fault report for overcurrent conditions.

The TPS2041BMDBVTEP utilizes an internal charge pump for gate drive, controlling power-switch rise and fall times to minimize current surges. The maximum standby supply current is a low 1 μA. The switch is housed in a 5-pin SOT-23 package, designed for surface mounting.

This component is suitable for applications where robust power management and protection are critical, such as USB ports and other power delivery systems requiring reliable current limiting and fault handling.
