The TPS201x family of power-distribution switches is intended for applications where heavy capacitive loads and short circuits are likely to be encountered. The high-side switch is a 95-mΩ N-channel MOSFET. Gate drive is provided by an internal driver and charge pump designed to control the power switch rise times and fall times to minimize current surges during switching. The charge pump operates at 100 kHz, requires no external components, and allows operation from supplies as low as 2.7 V. When the output load exceeds the current-limit threshold or a short circuit is present, the TPS201x limits the output current to a safe level by switching into a constant-current mode. Continuous heavy overloads...

| On-state resistance (typical) | 95 mΩ |
|---|---|
| Operating voltage range | 2.7 V to 5.5 V |
| Maximum standby current | 10 mA |
| Operating junction temperature range | -40°C to 125°C |
The typical short-circuit current limit for the TPS2010 is 0.4 A.
A thermal protection circuit shuts the switch off if the junction temperature reaches approximately 180°C.
No, the internal charge pump requires no external components and operates at 100 kHz.
