Description about Ic components VND5004A-E and VND5004ASP30-E Features
The electronic components VND5004ATR-E and electronic component VND5004ASP30-E are devices made using STMicroelectronics VIPower
technology. They are intended for driving resistive or inductive loads with one side connected to ground.
Active VCC pin voltage clamp and load dump protection circuit protect the devices against transients on the Vcc pin (see ic components ISO7637 transient compatibility table). These devices integrate an analog current sense which delivers a current proportional to the load current (according to a known ratio) when CS_DIS is driven low or left open. When CS_DIS is driven high, the CURRENT SENSE pin is high impedance.
Output current limitation protects the devices in overload condition. In case of long duration overload, the devicesa limit the dissipated power to a safe level up to thermal shut-down intervention. Thermal shut-down with automatic restart allows the device to recover normal operation as soon as a fault condition disappears.

Function about Electronic components LM101A/LM201A/LM301A
Electronic components LM101A/LM201A/LM301A provides better accuracy and lower noise in high impedance circuitry. The low input currents also make it particularly well suited for long interval integrators or timers, sample and hold circuits and low frequency
waveform generators. Further, replacing circuits where matched transistor pairs buffer the inputs of conventional IC op amps, it can give lower offset voltage and
a drift at a lower cost.
The ic components LM101A is guaranteed over a temperature range of
55°C to +125°C, the LM201A from
25°C to +85°C, and
the electronic component LM301A from 0°C to +70°C.

description information of electronic components lm358dr
These devices consist of two independent,high-gain, frequency-compensated operational
amplifiers designed to operate from a single supply over a wide range of voltages. Operation from split supplies also is possible if the difference between the two supplies is 3 V to 32 V (3 V to 26 V for the electronic components LM2904), and VCC is at least 1.5 V more positive than the input common-mode voltage. The low supply-current drain is independent of the magnitude of the supply voltage.
Applications include transducer amplifiers, dc amplification blocks, and all the conventional operational amplifier circuits that now can be implemented more easily in single-supply-voltage systems. For example, these devices can be operated directly from the standard 5-V supply used in digital systems and easily can provide the required interface ic components without additional ±5-V supplies.

Introduction to the function about Diode
1.A diode allows current to flow in one direction onl
2.It consists of 2 pieces of silicon, each 'doped' with a different chemical (e.g. phosphorus and boron) to make one more positively charged than the other. The more positively charged piece attracts negatively charged electrons more than the other and this permits a one-way flow.
3 Diodes need greater than 0.7 volts to work.
4.To convert AC to DC, you must use a full wave rectifier that consists of 4 linked diodes.:
