DESCRIPTION
The TJ2205X is dual-channel High-Side MOSFET switches optimized for general-purpose power
distribution requiring circuit protection.
The TJ2205 series support the following USB requirements. Each of the two channels supplies up to
500mA as required by USB downstream devices. Each switch’s low on-resistance meets USB voltage
drop requirements. Fault current is limited to typically 1.2A. Flag output indicates fault conditions to the
local USB controller. Soft-start prevents the transient voltage drop on the upstream port that can occur
when the switch is enabled in bus-powered applications. Under voltage lockout (UVLO) feature disables
the output switches until a valid input voltage. Also the TJ2205 include thermal shutdown to prevent switch
failure from high-current loads.
