3 Description

The TPS6602x is a full-featured

power

switch

multiplexer that contains an integrated 5-V Source

power path and a 4-V to 22-V Sink power path. The

5-V Source path limits the output current to a safe

level by operating in a constant-current mode when

the output load exceeds the selected current-limit

threshold.

Each

power

path

supports

overtemperature

and

reverse

current

protection.

VBUS has overvoltage protection with its level being

set by an optional external resistor divider. If no

overvoltage protection is desired, it may be disabled

by grounding the OVP terminal. The TPS6602x series

supports a fault pin that indicates overcurrent and

overtemperature events.

TPS6602x series also supports a high voltage VBUS

LDO regulator (3.3-V or 5-V per device type) useful

for supplying power to the device and other system

components

when

operating

in

dead

battery

conditions. The TPS66020 regulates to 3.3-V and the

TPS66021 regulates to 5-V.
