Battery charger using a depletion mode transistor to serve as a current source |
摘要 |
In a battery charger using a depletion mode transistor to serve as a current source, the depletion mode transistor is self-biased for generating a charging current to charge a battery, thereby requesting no additional control circuit to control the depletion mode transistor, reducing the circuit size, and lowering the cost.
