The AW328xx features an ultra-low 28m (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 29VDC. The default OVP threshold is 5.95V (AW32801), 6.8V (AW32805), 9.98V (AW32809) and 14V (AW32812), the OVP threshold can be adjusted from 4V to 20V through external OVLO pin. The device features an open-drain output ACOK, when VIN_UVLO < VIN < VIN_OVLO and the switch is on, ACOK will be driven low to indicate a good power input, otherwise it is high impedance. This device features over-temperature protection that prevents itself from thermal damaging. The AW328xx is available in a RoHS compliant 12-bump 1.34mm × 1.78mm WLCSP.
