AW32405CSR

The AW32405 OVP load switch features surge protection, an internal clamp circuit protects the device from surge voltages up to ±100V. The AW32405 features an ultra-low 13mΩ (typ.) Rdson nFET load switch. When input voltage exceeds the OVP threshold, the switch is turned off very fast to prevent damage to the protected downstream devices. The IN pin is capable of withstanding fault voltages up to 35VDC. The default OVP threshold is 6.8V, the OVP threshold can be adjusted from 4V to 20V through external OVLO pin. The device features an open-drain output ACOK (overline): when the voltage at the N_UVLO pin is less than the voltage at the N pin, which is less than the voltage at the N_OVLO pin, and the switch is on, ACOK (overline) will be driven low to indicate a good power input, otherwise it is high impedance. This device features over-temperature protection.
