The Power MUX 2 Click Board™ is a compact add-on board with a highly configurable power mux. This board features the TPS2120, a dual-input single-output power multiplexer with an automatic switchover feature from Texas Instruments. This Click Board™ prioritises the main supply when present and quickly switches to auxiliary supply when the main supply drops. During switchover, the voltage drop is controlled to block reverse current before it happens and provide uninterrupted power to the load with minimal hold-up capacitance. This Click Board™ is suitable for backup and standby power applications, input source selection, and various systems having multiple power sources.
The Power MUX 2 Click Board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click Board™ comes as a thoroughly tested product, ready to be used on a system equipped with the mikroBUS™ socket.
