slvs190b is a high-side mosfet switch from ti company. it has a low on-resistance of 33-mΩ and can operate in a range of 2.7v to 5.5v. this switch also has short-circuit protection, overcurrent logic output, logic-level enable input and other functions.
The TPS203x family consists of power distribution switches intended for applications with heavy capacitive loads and potential short circuits. These devices are 50-mΩ N-channel MOSFET high-side power switches controlled by a logic enable compatible with both 5-V and 3-V logic levels.
| Input Voltage Range | 2.7 V to 5.5 V |
|---|---|
| Maximum Standby Supply Current | 10 µA |
| On-State Resistance | 50 mΩ |
| Operating Junction Temperature Range | -40 °C to 125 °C |
The typical rise time is 6.1 ms.
It limits output current to a safe level by switching into constant-current mode when an overload or short is present.
