Adjustable Overvoltage Protectors from Maxim

Additionally, the devices enhance design flexibility by allowing designers to adjust the overvoltage-protection threshold with optional external resistors to any voltage between 4V and 12V. The MAX14527/MAX14528 are ideal for cell phones, media players, PDAs, and other portable applications requiring accurate overvoltage protection.

These OVPs integrate thermal shutdown protection to prevent overcurrent damage, and they provide ±15kV ESD protection (Human Body Model) when the input is bypassed with a 1microfarad capacitor to ground. Packaged in a lead-free, 2mm x 2mm, 8-pin TDFN, the MAX14527/MAX14528 are fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range.
