Active high-side switch with 2.5 A continuous rating
The TPS2554DRCR: The output is an N-channel MOSFET with an on/off control interface and a status flag output that asserts when the switch is in current-limit or thermal-shutdown.
73 mOhm Rds(on) — voltage drop and thermal budget
At 2.5 A the typical drop across the switch is 73 mOhm, dissipating power within the package rating.
Adjustable current limit and fault protection set
The current limit is set with an external resistor from the ILIM pin to ground, allowing the threshold to be trimmed below the maximum. The protection block includes.
The wide range also covers cold-start conditions down to -40°C without output degradation.
