The AP2821KTR-G1 is an integrated high-side power switch designed for applications requiring efficient power management. It features an N-channel MOSFET with a low on-resistance of 120mΩ at 5.0V, meeting USB voltage drop requirements.
This device includes essential protection features such as soft-start to manage inrush current, over-current protection with fold-back, and thermal shutdown to prevent failure during hot-plugging. An under-voltage lockout (UVLO) ensures the device remains off until a valid input voltage is present. It also provides no reverse current when power is off.
The AP2821KTR-G1 is suitable for USB power management, self-powered hubs, hot-plug power supplies, and battery-charger circuits. It is supplied in a compact SOT-23-5 package, designed for surface mounting.
Key electrical characteristics include a typical supply current of 35μA and a shutdown current of less than 1μA. The current limit is set at 2A with fold-back protection. ESD protection is provided, meeting IEC61000-4-2 standards for both air and contact discharge.
