Over-Voltage Protection Load Switch
Descriptions
The WS3210 features a low RON internal High Voltage
Switch and an input range of absolute maximum 30V.
An internal input clamp is capable of shunting surge
voltage >80V, protecting downstream components and
enhancing system robustness. The WS3210 features
Over-Voltage Protection (OVP) that shuts off the
internal Switch if input voltage exceeds the Fixed OVP
threshold 5.85V / 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.
