A relay IC controller is an electromagnetic switch that will be used when you want to use a low voltage circuit to turn on and off a light bulb that is connected to a 220V power supply. The current required to run the relay coil is more than can be supplied by various integrated circuits such as Op-Amp, etc. The relays have unique properties and are replaced by solid state switches that are strong that the solid state devices . High current capacities, the ability to withstand ESD insulation and drive circuit are the unique properties of the relays. There are several ways to handle relays.
Some of the CI relay controllers are as follows.
• High-side switch switch
• Low side tilt switch driver
• Bipolar NPN transistor controller
• N-channel MOSFET controller and
• Darlington Transistor Controller
• ULN2003 Controller
Relay controller IC circuit
Relays are components that allow a low-power circuit to control the signals or to change the high current ON and OFF that must be electrically isolated from the control circuit.
Required Components
• Zener diode
• Relay 6-9V
• 9V battery or DC power supply
• Transistor 2N2222
• 1K ohm resistance
• Second input voltage source
In order to drive the relay, the transistor is used and only less power can be used to obtain the driven relay. Since, the transistor is an amplifier so the low conductor receives enough current to make more current flow from the emitter of the transistor to the collector. If the base once obtains the power that is sufficient, then the transistor leads from the Emitter to the Collector and feeds the relay.
The emitter-collector channel of the transistor will open even though no input current or voltage is applied to the transistor base cable. Therefore, the current blockage flows through the relay coil.
The emitter-to-collector channel will open and allow current to flow through the relay coil if sufficient current or voltage is applied as input to the base wire. AC or DC can be used to power the relay and circuit. Delays are electromagnetic devices that allow low power circuits to switch a high current on and off devices with the help of an armature that is moved by an electromagnet.
The driver circuit is used to boost or amplify signals from micro-controllers to control power switches in semiconductor devices. Control circuits take functions that include isolating the control circuit and power circuit, detecting malfunctions, storing and reporting faults to the control system, acting as a precaution against faults, analyzing sensor signals and creating auxiliary voltages.
