AW32405
May 2019 V1.0
Over-Voltage Protection Load Switch with Surge Protection
Features
General Description
Surge protection
The AW32405 OVP load switch features surge
IEC 61000-4-5: ±100V
Integrated low Rdson nFET switch: typical 13
protection, an internal clamp circuit protects the
device from surge voltages up to ±100V.
l
6A continuous current capability
Default Over-Voltage Protection (OVP) threshold
AW32405: 6.8V
OVP threshold adjustable range: 4V to 20V
Input system ESD protection
tia 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
IEC 61000-4-2 Contact discharge: ±8kV
IEC 61000-4-2 Air gap discharge: ±15kV
n withstanding fault voltages up to 35VDC.
The default OVP threshold is 6.8V, the OVP
Input maximum voltage rating: 35VDC
Fast turn-off response: typical 50ns
Over-Temperature Protection (OTP)
Under-Voltage Lockout (UVLO)
WLCSP 1.215×1.775-12B package
Applications
Smartphones
Tablets
Charging Ports
e threshold can be adjusted from 4V to 20V through
external OVLO pin.
fid 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.
nThis device features over-temperature protection
that prevents itself from thermal damaging.
