TPS2041, TPS2051 are 135-mΩ N-channel MOSFET high-side power switches with 500mA continuous current, short-circuit and thermal protection and overcurrent logic output. They are intended for applications where heavy capacitive loads and short circuits are likely to be encountered.
The TPS2041 and TPS2051 are N-channel MOSFET high-side power switches designed for applications with heavy capacitive loads and short circuits. They feature an internal charge pump to minimize current surges and operate from supplies as low as 2.7 V. The devices are available in 8-pin SOIC and PDIP packages.
| On-state resistance (max) | 135 mΩ |
|---|---|
| Continuous output current | 500 mA |
| Current limit (typical) | 0.9 A |
| Operating temperature range | -40°C to 85°C |
| ESD protection (Human Body Model) | 2 kV |
The charge pump allows operation from supplies as low as 2.7 V.
It switches into a constant-current mode and pulls the overcurrent logic output low.
A thermal protection circuit shuts off the switch until it cools down.
