The cell voltage is bq to allow a system host to measure individual series elements bq the battery. Storage temperature range, Tstg. Bq299312 a current limit fault or watch dog timer fault occurs, the state is latched.
Provides thermistor bias current. Precharge and 0 V Charging–Theory of Operation. I 2 C-Bus Read from bq The WDI input is required as bq time base for delay timing when determining overload and short-circuit delay periods and. After start up, when the REG voltage is above 2. The output voltage includes the scale factor error and offset and is represented by: Data out hold time after clock low.
The bq interface allows the host to observe and control the current status of the bq Clock low to data out bq In overload and short-circuit conditions, the bq bq the FET drive off autonomously dependant on the bq configuration setting.
PACK positive terminal and alternative power source. Current sense negative terminal when discharging relative to SR2. On entry to this mode, all registers are masked off keeping their. Short-circuit current threshold voltage and delay for discharge. The bq provides safety protection for overcharge.
Sense voltage input terminal for least positive cell, balance current input for least positive cell and return balance. Bq229312 to Battery Management Host. Sense voltage input terminal for second most positive cell, balance current input for second bq positive cell.
If an oscillator bq condition is identified, then the. During normal operation, the regulator limits output current to typically 50 mA. Short-circuit current threshold voltage and delay for charge. The cell balance control allows a small bypass path to be controlled for any one series element.

Current for cell balancing. OL detection threshold hysteresis. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The bq is always regarded as a slave. Bq is designed to work bq the bq AFE protection IC to maximize functionality and safety and minimize component count hq29312 cost in smart battery circuits. Output of scaled value of the measured cell voltage. D Programmable Threshold and Delay for Over. OC and SC protection: The overload threshold can be programmed from 50 mV to mV in. The delay time can be increased via the OLT register, which can be programmed for a bq of 1.
Clock low to data out valid. Cell Balancing Algorithm and Control.
The output voltage includes the offset and represented by: Pre-charge Control Fail-Safe Protection. Single Supply ; Settling Time: TOUT pass-element series resistance. Detail is described in the application section.
Sense voltage input terminal for second most positive cell, balance current input for second most positive cell. How bq recognize if i can reset BQ or not? Short-circuit current threshold voltage and delay for discharge.
D Medical and Test Equipment. The bq is a 2- 3- or 4-cell lithium-ion battery pack.
Output voltage, charge and discharge. GG Clock Never Starts. Anyway to fix it? The leads should be shorted together or the device placed bq conductive foam during storage or handling bq prevent electrostatic damage to the MOS gates. See Dissipation Rating Table.
