The TPS202x family of power distribution switches is designed for applications where heavy capacitive loads and short circuits are likely to be encountered. These devices are 50-mΩ N-channel MOSFET high-side power switches with features such as short-circuit and thermal protection, overcurrent logic output, etc. They operate in a range of 2.7V to 5.5V and have a logic-level enable input compatible with 5V and 3V logic.
The TPS202x family of power distribution switches is intended for applications where heavy capacitive loads and short circuits are likely to be encountered. These devices are 50-mQ N-channel MOSFET high-side power switches controlled by a logic enable compatible with 5-V and 3-V logic.
| On-state resistance | 50 mQ |
|---|---|
| Operating voltage range | 2.7 V to 5.5 V |
| Maximum standby supply current | 10 uA |
| ESD protection (Human Body Model) | 2-kV |
The limits are 0.3-A for TPS2020, 0.9-A for TPS2021, 1.5-A for TPS2022, 2.2-A for TPS2023, and 3-A for TPS2024.
The device operates with an input voltage ranging from -0.3 V to 6 V.
The power switch shuts off when the junction temperature rises to approximately 140°C.
The rise and fall times are typically in the 2-ms to 9-ms range.
