Product Overview
BQ7693003DBTR is a Texas Instruments battery monitor AFE in the Power_Management category. The BQ7693003DBTR option supports 6-10 series cells and is described for 36 V battery packs. It provides an I2C-compatible digital interface for host controller communication, using a 7-bit I2C address of 0x08, with CRC support and a 3.3 V LDO output.
The monitoring structure includes an internal ADC for cell voltage measurement and temperature measurement, covering die temperature and an external thermistor. A separate internal ADC measures pack current for the coulomb counter function. The device directly supports up to three 103AT thermistors.
Protection and control functions include integrated cell balancing FETs, charge and discharge low-side N-channel FET drivers, overcurrent in discharge protection, short-circuit in discharge protection, and overvoltage and undervoltage protection. The device supports Li-ion and Li-iron phosphate battery chemistries and lists a maximum supply voltage absolute maximum up to 108 V.
The part is offered as BQ7693003DBTR in tape-and-reel packaging. It uses the 30-pin 30-TSSOP DBT package, with 7.80 mm x 4.40 mm nominal body size and 1.2 mm package height. EEPROM programming is not required because the I2C address, LDO voltage, and other settings are permanently stored.
