Evaluation Kit for the MAX38886

Product Details

The MAX38886 evaluation kit (EV kit) evaluates the MAX38886 IC. The MAX38886 is a super cap backup regulator designed to transfer power between a super cap and a system supply rail. When the main battery is present and above the minimum system supply voltage, the regulator charges the super cap at up to a 500mA rate. Once the super cap is charged, the circuit draws only 3µA of current while it maintains the super cap in its ready state. When the main battery is removed, the regulator prevents the system from dropping below the minimum operating voltage, discharging the super cap at up to a 2.5A peak inductor current. Multiple MAX38886 ICs can be connected in parallel for higher current applications. The MAX38886 is externally programmable for mini- mum and maximum super cap voltage, minimum system voltage, and maximum charge and discharge currents. The internal DC-DC converter requires only a 1µH inductor and a 22µF capacitor.
