High-Frequency,  
Low-Cost SMBus Chargers  
General Description  
Features  
S Low-Cost SMBus Charger  
The MAX17035/MAX17435/MAX17535 integrated multi-  
chemistry battery chargers IC simplify construction  
of accurate and efficient chargers. The MAX17035/  
MAX17435/MAX17535 provide SMBusK-programmable  
charge current, charge voltage, input current limit, relearn  
voltage, and digital readback of the IINP voltage. The  
MAX17035/ MAX17435/MAX17535 utilize a charge pump  
to control the adapter selection n-channel MOSFETs  
when the adapter is present. When the adapter is absent,  
the charge pump is shut down and a p-channel MOSFET  
selects the battery.  
S High Switching Frequency (1.2MHz, 0.85MHz,  
0.5MHz)  
S Internal Boost Switches  
S SMBus-Programmable Charge Voltage, Input  
Current Limit, Charge Current, Relearn Voltage,  
and Digital IINP Readback  
S Single-Point Compensation  
S Automatic Selection of System Power Source  
Adapter n-channel MOSFETs Driven by an  
Internal Dedicated Charge Pump  
Adapter Soft-Start  
S ±0.ꢀ4 Accurate Charge Voltage  
S ±2.54 Accurate Input Current Limiting  
S ±±4 Accurate Charge Current  
The MAX17035/MAX17435/MAX17535 provide up to 7A  
of charge current to 2, 3, or 4 lithium-ion (Li+) cells in  
series. The charge current, and input current-limit sense  
amplifiers have low offset errors and can use 10mI  
sense resistors. The MAX17035/MAX17435/MAX17535  
fixed-inductor ripple architecture significantly reduces  
component size and circuit cost.  
S Monitor Outputs for  
AC Adapter Current (±24 Accuracy)  
Battery Discharge Current (±24 Accuracy)  
AC Adapter Presence  
The MAX17035/MAX17435/MAX17535 provide a digital  
output that indicates the presence of the adapter, an  
analog output that indicates the adapter or battery  
current, depending upon the presence or absence of  
the adapter, and a digital output that indicates when the  
adapter current exceeds a user-defined threshold.  
S AC Adapter Overvoltage Protection  
S 11-Bit Battery Voltage Setting  
S 6-Bit, Charge-Current Setting/Input Current Setting  
S Improved IINP Accuracy at Low Input Current  
The MAX17035 operates with a switching frequency of  
1.2MHz. The MAX17435 switches at 850kHz, and the  
MAX17535 switches at 500kHz.
