MAX8900A Evaluation Kit Evaluates: MAX8900A/MAX8900B General Description Features S 3.25MHz Switching Li+/Li-Poly Battery Charger The MAX8900A evaluation kit (EV kit) is a fully assembled and tested circuit for evaluating the MAX8900A switch- S JEITA Battery Temperature Monitor Adjusts Charge Current and Termination Voltage mode Li+/Li-Poly charger with 22V input rating and JEITA* battery temperature monitoring. The MAX8900A On-Board 3380K NTC Thermistor charges a 1-cell lithium-ion (Li+) or lithium-polymer On-Board Potentiometer Allows Easy Evaluation (Li-Poly) battery. The MAX8900A delivers up to 1.2A of current to the battery from a 3.4V to 6.3V supply. External S Battery Fast-Charge Current-Limit Adjustment Range of 50mA to 1200mA resistors and potentiometers adjust the fast-charge current and the prequalification and done current thresh- Dynamic Charge Current Programming Using MOSFET and Resistor Array on the EV Kit olds. A JEITA battery temperature monitor adjusts Potentiometer Adjustment Available charge current and termination voltage. S Prequalification and Done Threshold Adjustment The MAX8900A EV kit comes with the MAX8900A Range of 10mA to 200mA installed, but can also be used to evaluate the MAX8900B Dynamic Charge Current Programming Using with IC replacement of U1.
