Diodes AP9050 protection interface

The AP9050 from Diodes is a dedicated protection interface designed to guard the latest generation of power management ICs against overvoltages.

Comprising an LDO regulator and an n-channel power FET, the device controls supply current delivery to the PMIC, switching it on in the presence of a valid wall adapter or USB supply voltage and immediately off in the event of any overvoltage detection.

With an input supply range of 3 to 30 V, the device will safeguard a variety of portable products including smartphones, mobile phones and netbooks. Employing multi-die technology and a dual exposed pad DFN2020-6 package, the device offers lower power dissipation and higher efficiency than alternative zener shunt regulators, resulting in less heating and improvements in overall system reliability.

The interface does not require a bypass capacitor on the output and operates consistently across the temperature range of -40 to +85°C.
