TPS2066D Description

Short technical summary and product information.

The Texas Instruments TPS2066D is a versatile 2-channel power distribution switch designed to handle demanding applications where capacitive loads and short circuits are common. Each switch incorporates a 70mΩ N-channel MOSFET, providing efficient power delivery.

 

This device operates within a voltage range of 2.7V to 5.5V and offers a continuous current rating of 1A per channel. Key features include accurate current limiting (1.1A min, 1.9A max), thermal and short-circuit protection, undervoltage lockout (UVLO), and a deglitched fault report. The integrated charge pump controls rise and fall times, minimizing current surges during switching.

 

The TPS2066D is available in an 8-SOIC package, suitable for surface mounting. Its robust design makes it ideal for power-distribution systems requiring multiple power switches in a compact footprint. The device also features a low standby supply current of 1µA maximum.

 

Applications for the TPS2066D include USB ports, power management in consumer electronics, and general-purpose power switching where reliable current control and protection are essential.
