TPS2042DR Description

Short technical summary and product information.

The Texas Instruments TPS2042DR is a dual power distribution switch IC designed for robust power management in applications prone to heavy capacitive loads and short circuits. It integrates two N-channel MOSFET high-side power switches within a single 8-pin SOIC package.

 

Key electrical specifications include a continuous current rating of 500mA per channel and a typical on-resistance of 80mΩ. The device operates over a wide voltage range of 2.7V to 5.5V and features a typical rise time of 2.5ms to minimize current surges during switching. Protection mechanisms include fixed current limiting, over-temperature shutdown, and undervoltage lockout (UVLO).

 

The TPS2042DR is suitable for general-purpose switch applications and features a logic-level enable input compatible with 5V and 3V logic. It provides a status flag for overcurrent events. The ambient operating temperature range is -40°C to 85°C.

 

This surface-mount device is available in an 8-SOIC package, making it suitable for various PCB designs. Its bidirectional switch capability and integrated protection features simplify power distribution system design.
