Description

The AP22950 is a uni-directional high-voltage power switch for USB PD featuring undervoltage lockout, overvoltage lockout, reverse current protection and overtemperature protection circuits.

The AP22950 features a low 30mΩ on-resistance and operates from 2.5V to 22.5V VBUS input voltage.

The reverse current protection features isolation from higher VINT than VBUS that allows supplying internal system power node from the highest voltage from multiple AP22950 that are connected together, which is suitable for portable devices that have multiple power inputs.

The AP22950 offers default 23V overvoltage protection threshold by default without resistor on OVLO and the threshold is adjustable from 4.0V to 23V by external resistor on OVLO pin. ACKb pin can be VBUS voltage status indicator.

The AP22950 is available in the U-WLB2515-15 package.
