SLVS190B is a high-side MOSFET switch produced by TI, which has a low on-resistance of 33mΩ, a 5-V logic power supply, short circuit protection and overcurrent logic output.
The TPS203x family of power distribution switches is designed for applications involving heavy capacitive loads and short circuits. These devices are 50-mΩ N-channel MOSFET high-side power switches controlled by a logic enable compatible with 5-V and 3-V logic. An internal charge pump provides gate drive, requiring no external components and allowing operation from supplies as low as 2.7 V.
| On-state resistance | 50 mΩ |
|---|---|
| Operating voltage range | 2.7 V to 5.5 V |
| Maximum standby supply current | 10 µA |
| ESD Protection (Human Body Model) | 2 kV |
| Ambient temperature range | -40 °C to 85 °C |
| Junction temperature range | -40 °C to 125 °C |
The typical rise time is 6.1 ms.
It limits the output current to a safe level by switching into a constant-current mode.
A thermal protection circuit shuts off the switch to prevent damage.
