DIODES INC. AP9060 overvoltage clamp for the protection of power management ICs (PMIC) in portable applications. Provided in the small form factor 1.1mm x 1.4mm x 0.8mm W-DFN1114-3 package, device supports a wide battery charger output range of 3V to 30V. Device will pass the voltage through to the PMIC only up to a safe clamp voltage limit, factory set at 11V. Device’s feedback loop maintains the clamped output voltage level by backing off the drive to its p-channel MOSFET switch. With an ultra low bias current, the device also minimizes self-heating, thereby further increasing product reliability.
