MAX1552 Complete Power IC for Low-Cost PDAs General Description
... VIN falls below 3.6V, LBO goes low, typically putting the system (µP) into a sleep state. The MAX1552 remains fully functional in this state and all outputs maintain normal operation. However, when in sleep mode, the system (µP) typically drives ENSD, ENC2, and ENLCD low, turning off COR2, SDIG, and ...
