MAX14634:Ultra-Low On-Resistance and Compact Bidirectional Battery Switches

Smallest Battery Disconnect Switches with Lowest RON for Up to 5A Applications

The MAX14634/MAX14680 bidirectional battery switches feature reverse blocking capability to isolate the battery from the system. These internal switches feature ultra-low 7mΩ (typ) on-resistance and operate from a +2.3V to +5.5V input voltage range, making these devices ideal battery-disconnect switches for high-capacity battery applications. The slew-rate controlled switches are also ideal for a large load capacitor as well as high-current load switching applications. 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 -40°C to +85°C extended temperature range.
