The TPS2048 and TPS2058 are quad power distribution switches from Texas Instruments. Their features include 135mΩ high side MOSFET switch, 250mA continuous current per channel, independent short circuit and thermal protection with overcurrent logic output, operating range of 2.7-V to 5.5-V, logic level enable input, typical rise time of 2.5ms, undervoltage lockout, maximum standby supply current of 20µA, bidirectional switch, available in 16-pin SOIC package, ambient temperature range of -40°C to 85°C, and 2-kV human-body-model, 200-V machine-model ESD protection.
The TPS2048 and TPS2058 are quad current-limited power-distribution switches designed for applications involving heavy capacitive loads and short circuits, such as notebook PCs and monitors. Each device incorporates four 135-mΩ N-channel MOSFET high-side power switches in a single 16-pin SOIC package.
| On-state resistance (Vinx = 5 V) | 135 mΩ |
|---|---|
| Continuous output current per switch | 250 mA |
| Operating input voltage range | 2.7 V to 5.5 V |
| Package type | 16-pin SOIC |
| Ambient temperature range | -40°C to 85°C |
The typical rise time is 2.5 ms.
It limits output current to a safe level by switching into constant-current mode and pulling the OCx logic output low.
