Texas Instruments BQ7693003DBTR

BQ7693003DBTR Description
The BQ7693003DBTR robust analog front-end (AFE) device serves as part of a complete pack monitoring and protection solution for next-generation, high-power systems, such as light electric vehicles, power tools, and uninterruptible power supplies. The BQ7693003DBTR is designed with low power in mind: Sub-blocks within the IC may be enabled/disabled to control the overall chip current consumption, and a SHIP mode provides a simple way to put the pack into an ultra-low power state.

BQ7693003DBTR Features
Pure digital interface Internal ADC measures cell voltage, die temperature, and external thermistor A separate, internal ADC measures pack current (coulomb counter) Directly supports up to three thermistors (103AT) Overcurrent in discharge (OCD) Short circuit in discharge (SCD) Overvoltage (OV) Integrated cell balancing FETs Charge, and discharge low-side NCH FET drivers Alert interrupt to host microcontroller 2.5-V or 3.3-V output voltage regulator No EEPROM programming is necessary High supply voltage abs max (up to 108 V) Simple 1PCTM compatible interface (CRC option) Random cell connection tolerant

BQ7693003DBTR Applications
Light electric vehicles: Ebikes, E-scooters, Pedelec, Pedal-assist bicycles Power and Gardening tools Uninterruptible power supplies Battery Backup and UPS Systems Wireless Base Station Backup Systems 12-V, 18-V, 24-V, 36-V, and 48-V Battery Packs
