LTC1627
Li-Ion batteries, with their high energy density, are becoming the chemistry of choice for designers of many handheld products. In response to this growing trend, the LTC1627 incorporates features optimized for such chemistry. For instance, the LTC1627 integrates a precision undervoltage lockout circuit that shuts itself down when the supply voltage dips below 2.5V, drawing only 6μA of quiescent current. This prevents damaging a Li-Ion battery ...
