Fe a t u re s  
The MAX1612/MAX1613 manage the bridge battery  
(sometimes called a hot-swap or auxiliary battery) in  
portable systems such as notebook computers. They  
feature a step-up DC-DC converter that boosts 2-cell or  
3-cell bridge-battery voltages up to the same level as  
the ma in b a tte ry. This volta g e b oos ting te c hniq ue  
reduces the number of cells otherwise required for a 6-  
cell plus diode-OR bridging scheme, reducing overall  
size and cost. Another key feature is a trickle-charge  
timer that minimizes battery damage caused by con-  
stant charging and eliminates trickle-charge current  
drain on the main battery once the bridge battery is  
topped off.  
♦ Reduce Battery Size and Cost  
♦ Four Key Circuit Blocks  
Adjustable Boost DC-DC Converter  
NiCd/NiMH Trickle Charger  
Always-On Linear Regulator (+28V Input)  
Low-Battery Detector  
♦ Low 18µA Quiescent Current  
♦ Selectable Charging/Discharging Rates  
♦ Preset Linear-Regulator Voltage  
5V (MAX1612)  
3.3V (MAX1613)  
These devices contain a highly flexible collection of  
independent circuit blocks that can be wired together  
in an autonomous stand-alone configuration or used in  
conjunction with a microcontroller. In addition to the  
boost converter and charge timer, there is a micropow-  
er linear regulator (useful for RTC/CMOS backup as  
well as for powering a microcontroller) and a high-pre-  
cision low-battery detection comparator.  
♦ 4V to 28V Main Input Voltage Range  
♦ Internal Switch Boost Converter  
♦ Small 16-Pin QSOP Package  
The two devices differ only in the preset linear-regulator  
output voltage: +5.0V for the MAX1612 and +3.3V for  
the MAX1613. Both devices come in a space-saving  
16-pin QSOP package.
