The TPS2043 and TPS2053 are triple power distribution switches with a maximum resistance of 135 mΩ, 5 V input, and a continuous current of 500 mA per channel. It has short circuit protection and overcurrent logic output, operating voltage range of 2.7 V to 5.5 V, logic level enable input, 2.5 ms typical rise time, undervoltage lockout, 20 µA maximum standby supply current, bidirectional switch, available in 16-pin SOIC package, ambient temperature range of -40°C to 85°C, 2 kV Human-Body-Model, 200-V Machine-Model ESD protection, UL listed-File No. E169910.
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.
