The ISL6140 is an 8-pin, negative voltage thermal plug-in controller that allows boards to be safely inserted and removed from a live backplane. Inrush current is limited to a programmable externally controlled gate voltage value for N-channel transistors. The pass transistor is turned off if the input voltage is below the undervoltage threshold, or greater than the overvoltage threshold. A...

The fuel pressure gauge interface of the digitally controlled MAX1660 performs two basic functions for rechargeable battery pack management: fuel gauge, and pack overcurrent protection. It accurately monitors the charging and discharging current flowing through the battery pack and records each using two independent on-board coulomb counters. The contents of each counter are accessed through...

The MAX1665 provides protection against overvoltage, undervoltage, overcharge current, and discharge current for 2-cell, 4-cell lithium-ion (Li+) battery packs. Very low operating current ensures that cells are not overdischarged during long-term storage. The MAX1665 controls two external N-channel MOSFETs to limit the charge and discharge voltages. When charging is allowed, the ...

The UCC1913 family of negative high voltage circuit breakers provides complete power management, hot swap, and fault handling capabilities. The IC references a negative input voltage and connects to ground through an external drive resistor, which is essentially a current drive as opposed to a conventional voltage drive. The on-board 10V shunt regulator fails from the overvoltage protecti...
