This document introduces TI's TPS2xx series products, including their features and characteristics. This series of products has a wide range of applications.
The TPS204xB/TPS205xB power-distribution switches are designed for applications involving heavy capacitive loads and short circuits. These devices incorporate 70-mΩ N-channel MOSFET power switches controlled by logic enable inputs, with gate drive provided by an internal charge pump to minimize current surges during switching.
| Continuous output current limit | 500 mA |
|---|---|
| Operating voltage range | 2.7 V to 5.5 V |
| Thermal shutdown threshold | 135 °C |
The typical rise time is 0.6 ms.
Yes, a thermal protection circuit shuts off the switch if junction temperature rises due to continuous heavy overloads or short-circuits.
