The TPS2055ADRG4 from Texas Instruments is a current-limited power distribution switch designed for applications with heavy capacitive loads and potential short circuits. It features an 80mΩ high-side N-channel MOSFET switch, capable of delivering 250mA continuous current per channel.
The device operates within a voltage range of 2.7V to 5.5V and includes independent thermal and short-circuit protection with an overcurrent logic output. The enable inputs are CMOS and TTL compatible. It also incorporates undervoltage lockout (UVLO) and has a typical rise time of 2.5ms.
Packaged in an 8-SOIC surface-mount package, the TPS2055ADRG4 is suitable for various power distribution systems requiring multiple power switches. The switch limits output current to a safe level by entering a constant-current mode when the load exceeds the threshold or a short circuit occurs, indicated by the overcurrent (OCx) logic output going low. Thermal protection shuts off the switch if junction temperature rises due to continuous heavy overloads or short circuits, with automatic recovery once cooled.
