Description
The AW326XX family OVP load switch features surge protection, an internal clamp circuit protects the device from surge voltages up to ±200V.
The AW326XX features an ultra-low 33mΩ (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 (AW32601), 6.8V (AW32605) and 10.5V (AW32610), the OVP threshold can be adjusted from 4V to 20V through external OVLO pin.
This device features over-temperature protection that prevents itself from thermal damaging.
