Latest Patents
One of his latest patents is a "Single-power-transistor battery-charging circuit using voltage-boosted clock." This invention features a charge/discharge protection circuit that safeguards a battery from inadvertent shorting on a charger node. The circuit can connect to either a charger or a power supply of a portable electronic device. It utilizes a single n-channel power transistor that controls the channel between the battery and the charger node. The gate of this transistor is connected to the charger node via a gate-coupling transistor, which turns off the power transistor to provide battery isolation. The gate is driven by a voltage-boosted clock through a switch activated by an enable signal. Additionally, the enable signal activates a grounding transistor to ground the gate of the gate-coupling transistor. A comparator is employed to compare the voltages of the charger and battery nodes, with the compare output being latched to generate the enable signal. An inverse enable signal activates a second switch that drives the voltage-boosted clock to the gate of the gate-coupling transistor, effectively turning off the power transistor.
