EVALUATION KIT AVAILABLE MAX14634/MAX14680 Ultra-Low On-Resistance and Compact Bidirectional Battery Switches General Description Benefits and Features The MAX14634/MAX14680 bidirectional battery switches S Provide Efficient System Battery Switch feature reverse blocking capability to isolate the battery Integrated FET for Bidirectional Blocking from the system. These internal switches feature ultra- Ultra-Low 7mI (typ) R ON low 7mI (typ) on-resistance and operate from a +2.3V to Wide +2.3V to +5.5V Input Voltage Range +5.5V input voltage range, making these devices ideal Low Quiescent Current battery-disconnect switches for high-capacity battery S Save Space applications. The slew-rate controlled switches are also Integrated Pulldown and Logic Buffer Circuits ideal for a large load capacitor as well as high-current 12-Bump, 1.3mm x 1.7mm, 0.4mm Pitch WLP load switching applications. Package The devices are available in an ultra-small 12-bump (1.3mm x 1.7mm, 0.4mm pitch) WLP package. The tiny, low-profile package is suitable for space-limited portable device applications. The devices operate over the -40NC Ordering Information appears at end of data sheet. to +85NC extended temperature range.
