Pin Description
The LS05006VPQ33 is a protection device that helps prevent
damage to electronic products with USB Type-C ports. It protects
against short circuits, overvoltage up to 24 V, and electrostatic
discharge (ESD). Many USB Type-C products don’t meet the
Type-C specification, and some adapters that only provide 20 V to
V
BUS
can cause short circuits due to pin issues, twisting, or
moisture. Proper overvoltage protection, helps avoid damage to
the low -voltage silicon circuits in Type-C controllers.
LS05006VPQ33, safeguards the downstream low -voltage circuits
against overvoltage and IEC61000-4-2 ESD strike.
The LS05006VPQ33 has a CC pin pull-down resistor that helps
power up and charge mobile devices with dead batteries. Once
the system power is up, the device automatically cuts out the CC
pin pull-down resistor, allowing the Type-C controller’s CC pin pull-
down resistor to take over without confusing the power source.
Applications
■ Automatically processes
signals and works
transparently without
interference or burdening
Type-C controller operation.
■ Overvoltage protection for
four-channels (CCxI, SBUxI)
with 24 V tolerant switch
and IEC 61000-4-2 ESD
protection.
■ Up to 600 mA high current
capability for CC1/CC2
overvoltage protection FETs
to pass V

power.
■ Include integrated CC1/CC2
pull-down resistors to handle
mobile device’s dead battery
conditions.
■ Designed in a compact
package QFN3x3_20L

Note1: Measured on JESD51-7, 4-Layer PCB.
Note 2: The maximum allowable power dissipation is a function of the maximum junction temperature T
J_MAX
,
the junction to ambient thermal resistance θ
JA
, and the ambient temperature T
A
. The maximum allowable
continuous power dissipation at any ambient temperature is calculated by P
D_MAX
= (T

)/θ
JA
. Exceeding
the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into
thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage.
