摘要： A capacitance measurement circuit includes a charge module to charge a capacitor, a discharge module to hold the capacitor discharge at a constant current, and a control module. The control module includes a timer, a detecting sub-module, a trigger sub-module, and a computing sub-module. The detecting sub-module detects whether the capacitance is fully charged and detects voltages V and discharge current I when the capacitor discharges. The trigger sub-module triggers the charge module to stop charging the capacitor and triggers the timer starts to time a preset discharge time once the capacitor is fully charged. The computing sub-module computes any output voltage differences during the discharge time, and further computes the capacitance value of the capacitor.

摘要： A power circuit which is applicable to a data storage device. A boost circuit receives a first voltage and converts it to a second voltage. A charging and discharging circuit receives the second voltage and charges a charging capacitor. As long as a voltage detecting circuit detects that the second voltage exists, it outputs a first selection signal. When the voltage detecting circuit detects that the second voltage does not exist, it outputs a second selection signal and also outputs a signal to the charging and discharging circuit, to release a stored voltage. A voltage selection circuit will output the second voltage according to the first selection signal, or will output the stored voltage from the charging capacitor according to the second selection signal. Buck circuits convert the second voltage or the stored voltage to the different voltages required by a control chip of the data storage device.
