Embodiment 1

[0039] A method for burning and upgrading an electric power management IC, the method comprising:

[0040] S101: Cyclic burning and upgrading of the battery power IC through 20 channels;

[0041] S102: Calculate the first checksum of the upgrade;

[0042] S103: Compare and verify the first checksum.

[0043] In one of the embodiments, the step of comparing and verifying the checksum includes:

[0044] receiving the second checksum calculated by the computer terminal;

[0045] comparing the second checksum with the first checksum.

[0046] In one of the embodiments, after the comparison and verification of the first checksum, the method further includes:

[0047] If the comparison and verification results are consistent, stop the current burning upgrade;

[0048] If not, repeat the programming cycle.

[0049] In one embodiment, the checksum is obtained by accumulating 32 bytes before burning.

[0050] Specifically described from the aspect of hardware, the hardware secti...

Embodiment 2

[0069] A burning and upgrading device for a power management IC, the device comprising:

[0070] Main control upgrade module 100: used for cyclically burning and upgrading the battery power IC through 20 channels;

[0071] Calculation module 200, for calculating the first checksum of the upgrade;

[0072] A comparing module 300, configured to compare and verify the first checksum.

[0073] In one of the embodiments, the comparison module includes:

[0074] a receiving unit, configured to receive the second checksum calculated by the computer terminal;

[0075] A comparing unit, configured to compare the second checksum with the first checksum.

[0076] In one of the embodiments, the device also includes:

[0077] A judging module, configured to judge whether the comparison and verification results are consistent;

[0078] stop module, used to stop the current burning and upgrading if the judgment of the judging module is consistent;

[0079] The repeating programming mod...

Embodiment 3

[0082] A burning upgrade system for a battery management IC, the system comprising:

[0083] Battery power management chip 1;

[0084] The burner 2 communicates with the battery power management chip 1 through EV2300;

[0085] An oscilloscope 3 is connected with the burner 2 and monitors the burning;

[0086] The protection board 4 is connected with the battery power management chip 1 for protection.

Abstract

The invention relates to an electricity amount management IC burn upgrading method.The method comprises the steps that circulation burn upgrading is carried out on a battery electric quantity IC through 20 channels; a first checksum of upgrading is calculated; the first checksum is verified through comparison.The number of the burn upgrading channels is increased to 20 from 12, the test time of each piece of burn upgrading BQ management product is shortened to 2 S from 6.6 S, efficiency is improved by 230%, and the efficiency of a whole assembly line is improved by 66.

Description

technical field [0001] The invention relates to the field of battery power management, in particular to a method, device and system for burning and upgrading a power management IC. Background technique [0002] At present, the company's single-cell power management products often need to rework and re-burn new version files in the HDQ state (such as Apple products) or need to upgrade the BQ low version in the I2C state (such as BBK, OPPO products, E02977, etc.), and What our company can deal with is the use of 12-channel old calibration equipment. On the basis of TI's third-party hardware, use EV2300 for programming or upgrading, which is inefficient (it takes several minutes to complete the burning and upgrading of 12PCS) and low reliability. , the equipment failure rate is high, and the fast delivery required by customers cannot be met. In order to meet the rapid burning and upgrading of power management products, improve customer satisfaction and reduce the resource loss...
