TPS2101D Description

Short technical summary and product information.

The TPS2101D from Texas Instruments is a power mux designed to provide an uninterrupted output voltage during transitions between two independent power supplies. It integrates an N-channel MOSFET with a 250-mΩ on-resistance for higher main supply currents and a P-channel MOSFET for auxiliary power supplies delivering lower current for standby modes.

 

This device operates within a voltage range of 2.7 V to 4 V. It supports a main supply current of 500 mA and an auxiliary supply current of 10 mA. The TPS2101D is housed in an 8-SOIC package and is designed for surface mount applications.

 

Key features include advanced switch control logic, CMOS- and TTL-compatible enable input, and controlled rise, fall, and transition times. The TPS2101D is suitable for typical applications such as notebook and desktop PCs, as well as palmtops and PDAs, where reliable power management is critical.

 

It operates within an ambient temperature range of -40°C to 70°C. The component is supplied in an 8-SOIC package with a standard package quantity of 75 units per tube.
