19-3923; Rev 0; 1/06 KIT ATION EVALU AVA ILABLE SMBus Level 2 Battery Charger with Remote Sense General Description Features MAX8731 The MAX8731 is an SMBusTM programmable multichem- 0.5% Battery Voltage Accuracy istry battery charger. The MAX8731 uses a minimal 3% Input Current-Limit Accuracy command set to easily program the charge voltage, charge current, and adapter current limit. 3% Charge-Current Accuracy SMBus 2-Wire Serial Interface The MAX8731 charges one to four Li+ series cells and delivers up to 8A charge current. The MAX8731 drives Cycle-by-Cycle Current Limit n-channel MOSFETs for improved efficiency and Battery Short-Circuit Protection reduced cost. Low-offset current-sense amplifiers pro- Fast Response for Pulse Charging vide high accuracy with 10m sense resistors. Fast System-Load-Transient Response The MAX8731 current-sense amplifiers provide high Dual-Remote-Sense Inputs accuracy (3% at 3.5A) and also provide fast cycle-by- cycle current-mode control to protect against battery Monitor Outputs for short circuit and system load transients. Adapter Current (4% Accuracy) The charger employs dual remote-sense, which reduces AC Adapter Detection charge time by measuring the feedback voltage directly 11-Bit Battery Voltage Setting at the battery, improving accuracy of initial transition into 6-Bit Charge-Current/Input-Current Setting constant-voltage mode. The MAX8731 provides 0.5% 8A (max) Battery Charger Current battery voltage accuracy directly at the battery terminal. 11A (max) Input Current The MAX8731 provides a digital output that indicates the presence of the AC adapter, as well as an analog output +8V to +26V Input Voltage Range that indicates the adapter current within 4% accuracy.
