POWER-GATE bi-directional solid state relays are well suited for a myriad traditional battery applications, as well as a single, high current gate for charge and discharge of lithium-ion batteries.  If you’re looking for a solid state method of uncoupling a battery from a load, but need bi-directional current flow for both charging and discharging, POWER-GATE bi-directional relays may be your answer.  Specifically designed for automotive, military, marine, aerospace, industrial, test fixtures, and various 12 and 24 volt OEM applications, POWER-GATE bi-directional solid state relays are engineered to handle shock and high-vibration environments. Our MOSFET-based devices are well suited for switching both large inductive loads and sensitive electronic equipment like power inverters and communications equipment. Unlike conventional mechanical relays, POWER-GATE relays have no contacts to arc, bounce, and degrade over time. Ultra-low trigger current makes POWER-GATE perfect for power sipping electrical systems where battery management is critical.

Devices can be customized for opto-isolation, latching, external Vcc, external status, logic feedback, and other various features. If you need to switch from a source to a load, and mechanical relays won’t cut it, POWER-GATE may be your solution.
