TPS2556DRBT Description

Short technical summary and product information.

The Texas Instruments TPS2556DRBT is an N-channel power distribution switch designed for applications where precise current limiting is essential, particularly in scenarios with heavy capacitive loads or short circuits. It offers an adjustable current limit ranging from 500 mA to 5 A, configurable via an external resistor.

 

Key electrical characteristics include a low typical on-resistance of 22 mOhm and a wide operating voltage range of 2.5 V to 6.5 V. The device provides essential fault protection features such as adjustable current limiting, over-temperature protection, and undervoltage lockout (UVLO). It also includes a status flag output that asserts low during overcurrent and overtemperature conditions.

 

Designed for surface mounting, the TPS2556DRBT comes in an 8-SON (3x3 mm) package with an exposed pad for enhanced thermal performance. The switch type is general purpose with an active-low enable input and a non-inverting input configuration. Its built-in soft start feature helps minimize current surges during turn-on.

 

This power switch meets USB current-limiting requirements and offers fast overcurrent response times, typically 3.5 µs. The maximum standby supply current is a low 2 µA, contributing to power efficiency in standby modes. System-level ESD protection is rated at 15 kV and 8 kV.
