Overvoltage protectors work as battery
chargers
MAX4880-MAX4884 overvoltage protection controllers have an integrated battery disconnect switch with a current-limit range of 0.525 to 1.1A.
New from Maxim Integrated Products, MAX4880-MAX4884 overvoltage protection controllers have an integrated battery disconnect switch with a current-limit range of 0.525 to 1.1A, depending on which part is used Integration of the current-limit switch in a 3 x 3mm TDFN package reduces both overall external system component count and necessary board space, making these devices ideal for such space-constrained applications as cell phones, digital still cameras, PDAs and MP3 players

Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
The MAX4880-MAX4884 provide overvoltage protection to +28V.
Overvoltage trip levels range from +4.5 to +5.6V, and undervoltage trip levels range from +2.55 to +4.35V.
Additional features include flag signals (overvoltage, overcurrent, battery voltage trip) and an internal charge pump.
Also featured are thermal shutdown protection, 15kV ESD protection, and a built-in startup delay that allows the adapter voltage to settle down before turning on the external MOSFET.
Furthermore, the the MAX4880 can be configured as a low-cost battery charger.
These overvoltage protection controllers are specified to operate over the extended -40 to +85C temperature range.
The MAX4880-MAX4884 are available in 3 x 3mm, 10-pin TDFN packages.
Prices start at $1.40 (1000-up, FOB USA).
