New Product Announcement AP23x1A/AP24x1A/ AP25x1A Improved Power Density 2A and 2.5A Single Channel Overcurrent protecting USB Power Switches
The AP23x1A/24x1A/25x1A series provides fast and accurate overcurrent protection for improved USB port protection.
They expand on the existing family of USB switches with their support of dual-purpose port applications in which a port is used for data communication between the host and peripheral devices, while simultaneously maintaining a charge for the battery of the peripheral device.
They are ideal for protection in
LCD TVs, monitors, set- top boxes, notebooks, E- readers and smartphones.
All variants feature built-in
soft-start and output discharge circuitry, as well as reverse current blocking and over- temperature protection.
If an overcurrent condition occurs, the AP23x1A/25x1A limits the output current while the AP24x1A latches off the output.
The Diodes' Advantage
The AP23x1A/24x1A/25x1A provides fast and accurate overcurrent protection for improved USB port protection
Fast, short-circuit response time: 2μs
Prevents unnecessary system shutdown or restart
improved system robustness
2A continuous Load versions with different OCP Constant current (AP23x1A) and latch-off (AP24x1A) Fault behavior can be optimized for different designs
Output discharge function
Provides controlled discharge of the output capacitor when disabled Improved robustness of system
Reverse current blocking, UVLO, overcurrent, over- temperature and short-circuit protection
Improves robustness of USB ports
Circuit Function
USB Ports protection 5V/3.3V Power Supply
