Adjustable Overvoltage Protectors from Maxim

Maxim has introduced the MAX14527/MAX14528 overvoltage protectors (OVPs) designed to protect low-voltage systems against voltage faults up to 28V. These devices employ an internal low, 100milliohm (typ) Ron MOSFET to prevent damage to circuitry from overvoltage conditions. This integration eliminates the need for an external n-channel MOSFET, thus saving board space and reducing cost.

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.
