- Bi-directional battery switches allow bidirectional flow of the current, which is useful for several operations as well as charging. Bi-directional battery switches possess reverse blocking capability, which helps in isolating the battery from the system.
- The logic control of a bi-directional battery switch is designed for interaction with the system controller and wireless charging receiver. This facilitates creation of a dual-input charger application in a single switch.
- In the ON position, bi-directional battery switches allow bi-directional current, while in the OFF position, they protect the battery from overcharging and excessive current drain. Also, they reduce battery power loss during normal operations.
- A bi-directional battery comes with a slew rate control, which makes it suitable for use in high-load bi-directional capacitors as well as switching applications With high current load

Miniaturization of Electronics Devices to Drive Global Bi-directional Battery Switch Market
- Printed circuit boards (PCBs) have limited space in devices such as smartphones, digital cameras, and data storage systems. Bi-directional battery switches are designed to save the PCB space in a majority of electronic devices instead of discrete MOSFET solutions that occupy around 26 square millimeters of space. In these devices, discrete MOSFET solutions utilize three components for battery isolation.
- Bi-directional battery switches come in wafer chip-scale packages (WCSPs), which are suitable for use in devices with limited space. Bi-directional battery switches are available in ultra-small sizes i.e. around 1.3 mm x 1.7 mm x 0.4 mm pitch. This saves around 91% of the printed circuit board unlike discrete MOSFETs.
- For instance, Vishay Intertechnology offers bi-directional battery switches that come in the size of 2.3 square millimeters. They save space and lower the overall count of components so as to simplify designs.
- Rising use of such space-saving devices is estimated to promote growth of the global bi-directional battery switch market during the forecast period.
