Hot Swap Controller Protects Batteries

Hot Swap Controller Protects Batteries
Linear Technology Corp.

The LTC4231 ultralow quiescent current (IQ) hot swap controller enables safe board or battery insertion and extraction from 2.7V to 36V systems. The device controls an external N-channel MOSFET to gently power up board capacitors, avoiding sparks, connector damage, and system glitches. Quiescent current is 4 µA during normal operation, dropping to 0.3µA in shutdown mode. To ensure low current operation, the under=voltage and overvoltage resistive dividers are connected to a strobed ground, lowering their average current draw by 50x. Available in 12-pin MSOP and 3 mm x 3 mm QFN packages, pricing starts at $2.25 each/1,000. A datasheet awaits at http://cds.linear.com/docs/en/datasheet/4231f.pdf
