MAX14634/MAX14680
Ultra-Low On-Resistance and Compact
Bidirectional Battery Switches
General Description
Benefits and Features
The MAX14634/MAX14680 bidirectional battery switches
feature reverse blocking capability to isolate the battery
from the system. These internal switches feature ultra-
low 7mI(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.
