Types of Diagrams Used to Read IC Datasheet for Beginners

There are four types of diagrams available for reading the IC datasheet effectively:

  1. GR Reading Block Diagram
  2. Flowchart Diagram
  3. ICs Function Block Diagram
  4. Voltage Testing Points and Fault Related Components Block Diagram
GR Reading Block Diagram: This diagram tells us the IC and all the parts in the line multimeter reading and what the reading will be on the line during cold testing if the line is functioning.

Flowchart Diagram: This diagram tells us what to check in which fault. This diagram shows the step by step flow chart of each fault so that we can read it and find the fault.

Are you ready to take your mobile phone repair skills to the next level? The article IC line testing techniques for electronics uncovers the secrets of hardware solutions from start to end, and guides you through the essential techniques and advanced methods to find faults in mobile phones and fix mobile hardware issues.

ICs Function Block Diagram: This diagram tells us how many lines the IC has and from which line the IC is doing what. To understand these lines we use a schematic diagram and IC datasheet of the mobile phone.

The diagram above shows the block diagram of bq 25601 IC current circuit flow. BQ IC stands for Berkeley Quantum. The bq 25601 IC is designed to manage input and output voltage and current for charging purposes in various smartphone models across brands like Redmi, Vivo, Oppo, Realme, Infinix, Techno, and Honor. Understanding this diagram is the first step to understanding an IC data sheet and its schematic diagram. The above diagram shows the IC lines and the readings given on them, then verifies if the line is correct. The above diagram shows the GR reading and voltage testing point where you can check the IC input and output line to verify whether the IC circuit is working or not.

Remember that the mobile PCB contains an unchecked component IC, but we can check its operation. To check the operation, we have to know how to read the schematic diagram or IC data sheet of the IC. With the help of the diagrams that I show you upon is easy for you to read the DATA sheet of the IC.
