Texas Instruments TPS2043/TPS2053 Triple Power-Distribution Switches Datasheet
The TPS2043 and TPS2053 are triple power-distribution switches designed for applications involving heavy capacitive loads and short circuits. Each device incorporates three 135-mΩ N-channel MOSFET high-side power switches controlled by logic enable inputs compatible with 5-V and 3-V logic. An internal charge pump drives the switches, allowing operation from supplies as low as 2.7 V without external components.
These devices provide robust protection mechanisms, including short-circuit and thermal protection. When an output load exceeds the current-limit threshold or a short is present, the switches limit output current to a safe level. A dual-threshold thermal trip circuit shuts off the switch if the junction temperature rises to approximately 140°C, isolating the fault without interrupting adjacent switches. The devices are available in a 16-pin SOIC package and operate over an ambient temperature range of -40°C to 85°C.
