2 results about "Discrete circuit" patented technology

A discrete circuit is an electronic circuit built out of discrete components, such as resistors, transistors, etc., instead of a single integrated circuit. Discrete circuits include individual electronic components including resistors, capacitors, and diodes, as opposed to integrated circuits, which include these components on a chip. Proponents of discrete circuits argue that because discrete components are larger, they carry a higher voltage and are less susceptible to electrical interference. Discrete circuits may also be desirable in developing application-specific designs, where it can occasionally be difficult to locate an appropriate off-the-shelf IC and the set-up cost of designing a new IC may be prohibitive. Alternatively, discrete circuitry may be preferred over ICs in a given case. Discrete circuits use individual resistors, capacitors, diodes, transistors, and other devices to achieve the circuit function. These individual or discrete parts must be interconnected. The usual approach is to use a circuit board. This method, however, increases the cost of the circuit. The board, assembly, soldering, and testing all make up a part of the cost.

Motor stalling protection driving circuit

PendingCN122092154AAvoid customization restrictionsImplement automatic stall protectionEmergency protective circuit arrangementsElectric machineHemt circuits
The invention discloses a motor locked-rotor protection driving circuit, which relates to the field of motor locked-rotor protection, and is characterized in that a first thermosensitive detection unit and a second thermosensitive detection unit are respectively connected between two output ends of a motor and a corresponding power switch unit in series; and the control module automatically pulls down the control end of the connected power switch unit to be below a cut-off threshold value during stalling, so that a corresponding current path is cut off, and automatic stalling protection is realized. Although the scheme is realized on the basis of discrete electronic elements, a current sampling resistor, a voltage comparator and a latch logic circuit which are necessary in a traditional discrete scheme are omitted through a thermal-electric direct linkage mechanism, and self-triggering protection can be completed only through few devices such as a thermistor, a bipolar transistor and a bias resistor; according to the invention, customization limitation of a special driving chip is avoided, defects of large size, high cost and low reliability of a traditional discrete circuit are overcome, a topological structure is obviously simplified, and system cost, size and failure rate are reduced.
