Latest Patents

Wong's latest patents include a USB charger using sensor-less current limit and a USB charger using current limit. The first patent describes a universal serial bus charger that features a connector for providing a connection to a voltage source. It includes an output voltage connector that supplies a charging voltage to a connected battery. The switching voltage regulator generates the charging voltage in response to the voltage source. Control circuitry monitors the actual charging current applied to the battery and provides a programmed current signal to maintain the charging current at a programmed level. If the actual charging current exceeds this level, the control circuitry enables the actual charging current to operate at a predetermined charge current limit. PWM control circuitry generates switching control signals to manage the operation of the switching voltage regulator based on the control circuitry's feedback.

The second patent also outlines a universal serial bus charger with similar features, emphasizing the importance of monitoring and controlling the charging current to ensure safe and efficient charging of connected devices.
