Bq is designed to work bq the bq AFE protection IC to maximize functionality and safety and minimize component count and cost in smart battery circuits. Sense voltage input terminal for most negative cell, return balance current for least positive cell.
Cell Balancing Algorithm and Control. The cell voltage is translated to allow a system host to measure individual series elements of the battery. Bq2912 out hold time after clock low. Cell balancing of each cell is performed via a cell bypass path, which is enabled via the internal control register accessible.

START condition hold time after which b29312 clock pulse is generated. The overload threshold can be programmed from 50 mV to mV in. SCLK pulse width low. Analog ground pin and negative pack terminal. The I 2 C compatible serial communications provides read and write access to the bq data area.
The open drain output has 1-mA current source drive with a maximum output voltage of 25 V. After start up, when the REG voltage is above 2. The bq does not support the general code of the I 2 C specification, and therefore does not return an ACK. Detail is bq2931 in the application section. Load and Short Circuit During Charge and.
I read the FAQ: Push-pull output discharge FET gate drive. This bit indicates a watchdog fault condition has occurred. The delay time can be increased via the OLT register, which can be programmed for a bq of 1.
The bq is always regarded as a slave. The cell balance control allows a small bypass bq293122 to be controlled for any one series element.
The short-circuit threshold can be programmed from mV to mV in mV steps with the default. In overload and short-circuit conditions, the bq OL detection threshold range, typical 1. See Dissipation Rating Table. If a FET is.
The bq acts as a slave device and does not generate clock pulses. The bq does not return a NACK for an invalid register address. The leads should be shorted together or the device placed in conductive foam during. The bq has three power modes, Normal, Sleep, and Ship. The WDI input is required as a time base for delay timing when determining overload and short-circuit delay periods and.
Current sense positive terminal when charging relative to SR2. This bit indicates a short-circuit in the charge direction. Sense voltage input terminal for second most positive cell, balance current input for second bq positive cell. The bq bq safety protection for overcharge, overload, short-circuit, overvoltage, and undervoltage conditions in conjunction with the battery management host. Current sense positive terminal when charging relative to SR2.
The bq does not support the address auto increment, which allows continuous reading and writing.
During normal operation, the regulator limits output current to typically 50 mA. The cell voltage is bq to allow a system host to measure individual series elements bq the battery. The bq is completely shut down as in the sleep mode.
When an overload or short-circuit fault is bqq29312, bq FETs are bq off. SCLK pulse width high. The bq interface allows the host to observe and control the current status of the bq Clock low to data out bq TOUT pass-element series resistance. Once V PACK is above the start-up voltage, it can fall down to the minimum supply voltage and still meet the specifications of the bq
