General Description
The TD9521 power switches are designed for USB
applications. The 25mΩ N‐channel MOSFET power
switch satisfies the voltage drop requirements of USB
specification.
The protection features include current‐limit protection,
short‐circuit protection, and over‐temperature protection.
The device limits the output current at current limit
threshold level. The over‐temperature    protection limits
the junction temperature below    140℃ in case of short
circuit or over load conditions. An enable input to enable
or disable the device.
