WS3202E WS3202E Over voltage and over current protection IC Http//:www.sh-willsemi.com Descriptions The WS3202E is an Over-Voltage-Protection (OVP) and Over-Current-Protection (OCP) device. The device will switch off internal MOSFET to disconnect IN to OUT to protect load when any of input voltage, input current over the threshold. The Over temperature SOT-23-6L protection (OTP) function monitors chip temperature to protect the device. The WS3202E is available in SOT-23-6L package. GND GND OUT 6 5 4 Standard products are Pb-free and Halogen-free.
