  • Description

    The JW®7105B is a current-limited programmable USB switches optimized for applications that require precise current limit, or to provide up to 3.3A of continuous load current during heavy loads/short circuits. These devices offer a programmable current-limit threshold between 550mA and 2.4A (Typ.) by an external resistor. The rise and fall times are controlled to minimize current overshoot or undershoot during switches on/off.

    The device has fast short-circuited response time for improved overall system robustness. It provides a complete protection solution, such as over-current protection, over-temperature protection and short-circuits protection, as well as controlled rise time and under-voltage lockout function. A7.5ms deglitch time on the open-drain Flag output prevents false over-current reporting.

    JW7105B offers TSOT23-5 packages.
