CH217 Key Features
- Built-in power switching tube, typical 70mΩ on-resistance
- The current limiting threshold can be adjusted by external resistors, supporting 400mA to 2.7A with ±10% typic
- Support power supply voltage 2.7V~5.5V
- Fast current limiting protection in case of output short circuit
- Low-power consumption, typical 50uA quiescent operating current
- Typical shutdown current is less than 1uA, with no reverse current at shutdown
