WS3221C-6/TR

WS3221C WS3221C Over-Voltage-Protection load switch with Http//:www.willsemi.com Adjustable OVLO threshold Descriptions The WS3221 is an Over-Voltage-Protection (OVP) load switch with adjustable OVLO threshold voltage. The device will switch off internal MOSFET to disconnect IN to OUT to protect load when any of input CSP-6L (Bottom View) voltage over the threshold. When the OVLO input set below the external OVLO select voltage, the WS3221 automatically chooses the internal fixed OVLO threshold voltage. The over voltage protection threshold voltage can be adjusted with external resistor divider and the OVLO threshold voltage range is 4~20V. The Over temperature protection (OTP) function monitors chip temperature to protect the device. Pin configuration (Top view) The WS3221 is available in standard CSP-6L Package. Standard products are Pb-free and Halogen-free.
