The XC8107 series includes an over-current limiting function with a high precision of ±10% and a high speed response time of 2µs and is available with fixed current limit values of 0.9A, 1.4A, 1.9A and 2.4A. Protection circuits such as a current limiting, reverse current prevention, thermal shutdown, under-voltage lockout (UVLO) and soft start contribute to the safe operation of the application.
A flag function is provided to allow monitoring of the switch state. The flag pin is an Nch open drain output which outputs a low level during detection of over-current or over-heating, or while the reverse current prevention function is operating. A small USP-6C package or a SOT-25 package can be selected as appropriate for the application.
