When a capacitor is faced with a decreasing voltage,it acts as a source: supplying current as it releases stored energy (current going out the negative side and in the positive side, like a battery). The ability of a capacitor to store energy in the form of an electric field (and consequently to oppose changes in voltage) is called capacitance.
The decoupling capacitors normally attached to the power rails must be actively discharged, to ensure proper control of the power‐down sequence and to complete power‐down in an acceptable time.
• Use a minimum of one capacitor per power pin, placed as physically close to the to the power pins of the IC as pos- sible to reduce the parasitic inductance. • Keep lead lengths on the capacitors below 6 mm between the capacitor endcaps and the ground or power pins. • Place the bypass capacitors on the same side of the PCB as the ICs.
Active capacitor discharge is essential for correct power‐down sequencing. Diodes Incorporated 2015 In Figure 1, the power sequencer’s EN output is connected to the enable pin on the DC‐DC regulator, and also to the gate of the P‐channel MOSFET (Q1).
nt of energy is dissipated in the circuit. Since this energy in the case of discharging comes from the capacitor you can draw simple conclusion from these experiments. Of the total energy drawn from the source in charging a capacitor, half is dissipated in the circuit and half is stored up in the capacitor i
Depending on the specific type of capacitor, the time it takes for a stored voltage charge to self-dissipate can be a long time (several years with the capacitor sitting on a shelf!). When the voltage across a capacitor is increased, it draws current from the rest of the circuit, acting as a power load.
