The MAX14527/MAX14528 overvoltage protectors (OVPs) guard against voltage faults up to 28 V. The devices employ an internal, 100-mΩ Ron MOSFET to prevent damage to circuitry from overvoltage conditions. The devices allow designers to adjust the OVP threshold with optional external resistors to any voltage from 4 to 12 V. The devices suit cell phones, media players, PDAs, and other portable applications.
These OVPs integrate thermal shutdown protection to prevent overcurrent damage, and they provide ±15-kV ESD protection when the input is bypassed with a 1-µF capacitor to ground. Packaged in a 2 x 2–mm 8–pin TDFN, they are specified from –40° to 85°C. ($0.90 ea/1,000 — available now.)
