The bq78350-R1 provides an accurate fuel gauge and state-of-health (SoH) monitor, as well as cell balancing and a full range of voltage-, current-, and temperature-based protection features. The bq78350-R1 offers optional LED or LCD display configurations for the capacity reporting. It also makes data available over its SMBus 1.1 interface. Battery history and diagnostic data is also kept within the device in non- volatile memory and is available over the same interface. 7 Pin Configuration and Functions 30-Pin DBT Package Pin Functions PIN I/O(1) DESCRIPTION NO. NAME 1 COM O Open Drain Output LCD common connection. Leave unconnected if not used. 2 ALERT I Input from the bq769x0 AFE 3 SDA I/O Data transfer to and from the bq769x0 AFE. Requires a 10-k pullup to VCC. 4 SCL I/O Communication clock to the bq769x0 AFE. Requires a 10-k pullup to VCC. Programmable polarity (default is active low) output to enable an optional precharge FET. This pin 5 PRECHG O requires an external pullup to 2.5 V when configured as active high, and is open drain when configured as active low. 6 VAUX AI Auxiliary voltage input. If this pin is not used, then it should be tied to VSS. 7 BAT AI Translated battery voltage input Active low input to sense system insertion. This typically requires additional ESD protection. If this 8 PRES I pin is not used, then it should be tied to VSS. A low level indicates application key-switch is inactive on position. A high level causes the DSG 9 KEYIN I protection FET to open. If this pin is not used, then it should be tied to VSS.
