SMB1360 CSIR and Battery Profile Identification

Application Note

1 Introduction 1.1 Objective The SMB1360 charger with fuel gauge allows the end-use customer to verify the correct CSIR, ensuring that charger settings and the battery profile match the targeted mobile equipment. This document describes the I2C address, data, and checksum encoding of the CSIR for the SMB1360 device.

1.2 References Reference documents are listed in Table 1. Table 1 Reference documents and standards Document number 80-NH006-1

Document name SMB1360 Device Specification

2 Identification of CSIR and Battery Profile The SMB1360 device is a charger with a fuel gauge suitable for mobile equipment and smartphones. The latest version of SMB1360 devices are programmed with CSIR identification. The CSIR must match the charge characteristics and battery profile to ensure safe operation and accurate state-of-charge (SoC) for the mobile equipment. The customer may choose to verify the CSIR and battery profile checksum to ensure that the correct version of the SMB1360 device is loaded. This application note provides the necessary I2C address and data information and describes the procedure used to verify that battery and charger profiles are programmed correctly. The customer can verify the CSIR number and checksum of the charger and two battery profiles, which are pre-programmed into the SMB1360 device.

2.1 Register description 2.1.1 CSIR and checksum identifier Table 2 identifies the I2C address and register data of the CSIR/checksum register for the SMB1360 device. These registers are located in the second block of the SMB1360 memory map, and they only apply to part identification values greater than or equal to CSIR#2293. This block consists of registers that store the fuel-gauge configuration and constants. The two LSBs of the 7-bit I2C slave address for this block should be set to 01b. If the default 8-bit slave address is XXXX X00X, then the slave address to read these registers will be XXXX X01X. The

2.2 CSIR and battery profile verification This procedure lets the customer verify that the battery profile values were programmed and the correct device is loaded. This includes reading the CSIR number and the checksum of the two battery profiles in the SMB1360 device.

Factory procedure: 

A four-digit hexadecimal checksum is programmed into two registers for each battery profile.



A four-digit CSIR number is programmed into the part.

Customer procedure: 

80-NH006-13 Rev. A

These values can be read by the customer during production to compare with values provided by Qualcomm Technologies, Inc. (QTI).
