The output voltage can be dynamically adjusted through the 5-bit digital-to-analog converter (DAC) inputs over a 0.600V to 2V range. The MAX1813 includes an internal multiplexer that selects between three different DAC code settings. The first two inputs are controlled by five digital input pins (D0D4). The third input is used for the suspend mode and controlled by two 4-level input pins (S0, S1). Output voltage transitions are accomplished with a proprietary precision slew-rate control that minimizes surge currents to and from the battery while guaranteeing "just-in-time" arrival at the new DAC setting.
