Over-Voltage Protection Load Switch
Descriptions
The WS3220 features a low RON internal 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.
