DESCRIPSION
The TJ2100X is single-channel High-Side
MOSFET switch optimized for adjustable current
limited power distribution requiring circuit
protection.
The TJ2100X series support the following USB
requirements. The TJ2100 series supply up to
2.5A as required by USB downstream devices.
Maximum continuous current can be different on
the types of package and ambient temperature.
Switch’s low on-resistance meets USB voltage
drop requirement. Flag output indicate fault
condition 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 TJ2100 include thermal shutdown to prevent
switch failure from high-current loads.

Note:
8. Maximum ambient temperature is a function of device junction temperature and system level considerations, such as
load current, power dissipation and board layout.
9. OFF is VEN0.8V and ON is VEN2.0V for the TJ2100H. OFF is VEN2.0V and ON is VEN0.8V for the TJ2100L.
10. TLIM is the response time to operate current limit when the peak value of the current is increased more than set limit
value.
11. It is recommended that current limit level set to 1.5 times more than constant current for a stable power
supply.
