MAX745 EVALUATION KIT AVAILABLE Switch-Mode Lithium-Ion Battery-Charger General Description The MAX745 provides all functions necessary for charging lithium-ion (Li+) battery packs.
It provides a regulated charging current of up to 4A without getting hot, and a regulated voltage with only ±0.
75% total error at the battery terminals.
It uses low-cost, 1% resistors to set the output voltage, and a low-cost N-channel MOSFET as the power switch.
The MAX745 regulates the voltage set point and charging current using two loops that work together to transition smoothly between voltage and current regulation.
The per-cell battery voltage re...
