Low-Power, Single/Dual-Level Battery Monitors Detailed Description The MAX6427–MAX6438 family is available with several monitoring options. The MAX6427/MAX6428/MAX6429 offer factory-trimmed battery-monitor thresholds, with a single low-battery output (see Figure 1). The MAX6430/MAX6431/MAX6432 also feature factory- trimmed thresholds, but have two low-battery ...
