摘要： A switch embedded integrated circuit for battery protection includes a MOSFET having a body diode, and a control logic circuit for switching the MOSFET and the direction of the body diode to control the charge current to and the discharge current from a battery. The control logic circuit turns off the MOSFET once any abnormal operation such as over-voltage and under-voltage happens, and turns on the MOSFET according to an OVPR threshold, an OVPR delay time, an UVPR threshold and an UVPR delay time. The OVPR threshold and the OVPR delay time are determined depending on the battery being coupled to a load or a charger, or floating.

摘要： A voltage reference circuit includes a current source unit, a voltage-difference creating unit, and a resistance ratio unit. The current source unit receives an input current source and produces two current sources in equal current. The voltage-difference creating unit includes a first MOS device and a second MOS device to respectively receive the two current sources, wherein the first MOS device and a second MOS device has a threshold voltage difference. The resistance ratio unit includes a first resistor and a second resistor coupled in cascade, wherein the threshold voltage difference is applied to the first resistor. By adjusting a ratio of the first resistor to the second resistor, the resistance ratio unit produces a voltage reference, which is also fed back to the current source unit to ensure that the first current source and the second current source are equal.
