Working Principles

TBD62308AFG,EL is based on the Darlington transistor configuration, which consists of two bipolar transistors connected in a way that amplifies the current gain. When an input signal is applied to the base of the first transistor, it controls the current flow through the second transistor, allowing or blocking the current path between the output and ground. This enables the IC to switch high currents with minimal input current.
