The ET3153A bidirectional battery switch features reverse blocking capability to isolate the battery from the system. The internal switch features ultra-low 6mΩ (Typ) on-resistance and operates from a 2.3V to 5.5V input voltage range, making this device ideal as a battery-disconnect switch for high-capacity battery applications. The slew-rate controlled switch is also ideal for a large load capacitor as well as high-current load switching applications.
The device is available in an ultra-small WLCSP12 package. The tiny, low-profile package is suitable for space-limited portable device applications.
The device operates over the -40 °C to +85 °C extended temperature range.
