    In this lesson,

    2

    00:00:01,300 --> 00:00:04,333

    we talk about the circuit related to the electricity leakage

    3

    00:00:04,366 --> 00:00:07,633

    and how to find the positive pole of the battery in the bitmap

    4

    00:00:12,966 --> 00:00:15,966

    We open Xinzhizao intelligent maintenance system

    5

    00:00:16,933 --> 00:00:21,533

    Open the bitmap, circuit diagram and component map of Xiaomi 10

    6

    00:00:28,133 --> 00:00:30,866

    Okay, we're going to find the positive pole of the battery,

    7

    00:00:31,066 --> 00:00:33,733

    first we're going to find the battery holder

    8

    00:00:34,066 --> 00:00:39,033

    We found the battery holder through the Chinese label, J5400,

    9

    00:00:52,566 --> 00:00:57,966

    We can also directly enter VBATT in the circuit diagram to find the battery holder

    10

    00:01:00,133 --> 00:01:01,766

    Then we open the bitmap,

    11

    00:01:02,533 --> 00:01:04,533

    at the same position above the bitmap,

    12

    00:01:05,200 --> 00:01:08,733

    we can see the battery holder J5400

    13

    00:01:28,700 --> 00:01:33,566

    The positive pole of the battery holder is called VBATT_CONN,

    14

    00:01:33,866 --> 00:01:35,800

    which is the name on the bitmap

    15

    00:01:38,433 --> 00:01:41,166

    We can click on it, after clicking it,

    16

    00:01:41,400 --> 00:01:43,066

    it will be highlighted in yellow

    17

    00:01:43,900 --> 00:01:48,966

    We can clearly see which components or chips are connected to the positive pole of the battery

    18

    00:01:49,933 --> 00:01:50,800

    For example,

    19

    00:01:50,866 --> 00:01:58,466

    the power supply from the battery holder leads to the components C5469, CR5402

    20

    00:01:59,266 --> 00:02:01,133

    We don't look at this resistor,

    21

    00:02:01,400 --> 00:02:04,366

    because one end of the resistor is not grounded,

    22

    00:02:04,600 --> 00:02:06,766

    Then we look at the yellow bright line,

    23

    00:02:06,933 --> 00:02:10,833

    which leads to the PIN 88 of the U5200

    24

    00:02:13,966 --> 00:02:15,933

    Let's see where it leads

    25

    00:02:17,333 --> 00:02:25,166

    It leads to components C5422, C5414, and R5405

    26

    00:02:26,066 --> 00:02:31,600

    It arrives at the chip U5500 through R5405,

    27

    00:02:31,900 --> 00:02:38,333

    and at the same time, it arrives at C5513, C5518

    28

    00:02:38,633 --> 00:02:41,433

    Okay, let's go back and see where it leads

    29

    00:02:41,833 --> 00:02:43,933

    Through this bitmap we know that

    30

    00:02:43,933 --> 00:02:46,700

    it only leads to one chip and four capacitors

    31

    00:02:52,733 --> 00:02:54,700

    Ok, that's it for this lesson
