Over-Voltage Protection Load Switch

Descriptions

The WS3220 features a low R_ONinternal High Voltage

Switch and an input range of absolute maximum 35V

DC. An internal Over-Voltage Protection (OVP) that

shuts off the internal Switch if input voltage exceeds the

fixed OVP threshold 6.2V / 6.8V / 10.5V / 14.0V. The

off-state Switch can disconnect the input pin to output

pin and protect output from the input high voltage stress.

Integrated Over-Temperature Protection (OTP) also

shuts off the Switch to protect the device.
