MAX8568A, MAX8568B Complete Backup-Management ICs For Lithium And NiMH Batteries

The MAX8568A MAX8568B backup-battery-management ICs are complete charging and backup switchover control solutions for PDAs, Smart Phones, and other smart portable devices. They charge both NiMH and rechargeable lithium battery types and feature programmable charge current and termination voltage. Separate optimized charge algorithms for both lithium and NiMH cells are included on-chip. The MAX8568A MAX8568B also manage backup switchover from a primary power source. An accurate onchip voltage detector monitors the main supply and backs up two system supplies (typically I/O and memory) when main power falls. On-chip drivers Switch external MOSFETs to disconnect the main supply from the system loads so the backup source is not drained. Low-voltage backup cells CAN be stepped up by an onchip synchronous-rectified, low-quiescent-current boost converter. Additionally, a low-quiescent-current LDO generates a second backup voltage. The MAX8568A LDO is preset to 2.5V while the MAX8568B LDO is preset to 1.8V. Both devices are supplied in 16-pin 3mm x 3mm thin QFN packages rated for -40C to +85C operation.
