What is the effect of increasing the input voltage on the circuit current?
In a linear circuit of fixed resistance, if we increase the voltage, the current goes up, and similarly, if we decrease the voltage, the current goes down. This means that if the voltage is high the current is high, and if the voltage is low the current is low.
What is low level input current?
The current into an input terminal when a specified low-level voltage is applied to that input.
What is low level of output?
The voltage level at an output terminal with input conditions applied that, according to the product specification, will establish a low level at the output. JESD99B, 5/07.
Why is an inrush current limiter circuit important?
The inrush current circuit stabilizes the high current requirement in the initial starting stage of the circuit. An inrush current limiter circuit limits the input current and keeps the source and the host device safer. Because a high inrush current increases the failure chances of the circuit and that needs to be rejected.
How does high inrush current affect a microcontroller?
High inrush current affects the source power supply. Often high inrush current drops the source voltage and results in a brownout reset for microcontroller-based circuitry. In few cases the amount of current supplied to the circuit gets beyond the acceptable maximum voltage of the load circuit, causing permanent damage to the load.
Why does the DC level vary with the input voltage?
The mains input AC voltage levels will be very linear with the DC output levels across the +/- lines of the circuit, or across the bridge rectifier output. Therefore, the DC level across the bridge rectifier, applied to the circuit will vary linearly in response to the varying AC mains input.
How does the current flow in a semiconductor?
When an external voltage is applied to a piece of N-type semiconductor material, current easily flows as the unbound electrons are attracted and pulled through the silicon by the external voltage. If the silicon is heavily doped with arsenic, many free electrons are available and a high amount of current will flow.
