Over-Voltage Protection Load Switch with Surge Protection
The AW327XX family OVP load switch features
IEC 61000-4-5: > 100V
Integrated low Rdson nFET switch: typical 24mΩ
surge protection, an internal clamp circuit protects
the device from surge voltages up to 100V.
5A continuous current capability
Default Over-Voltage Protection (OVP) threshold
OVP threshold adjustable range: 4V to 20V
tia The AW327XX features an ultra-low 24mΩ (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
Input system ESD protection
IEC 61000-4-2 Contact discharge: ±8kV
n withstanding fault voltages up to 35VDC.
The default OVP threshold is 6.8V (AW32705) and
IEC 61000-4-2 Air gap discharge: ±15kV
Input maximum voltage rating: 35VDC
e Fast turn-off response: typical 50ns
Over-Temperature Protection (OTP)
Under-Voltage Lockout (UVLO)

o Charging Ports
10.5V (AW32710), the OVP threshold can be
adjusted from 4V to 20V through external OVLO
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 AW327XX is available in a RoHS compliant
