Setup time for STOP condition.
Continuous total power dissipation. There are a couple of method by calibration circumstance. The bq does not support the address auto increment, which allows continuous reading and writing. Extend CELL output filter. Last pre-sleep entry configuration is valid.
GG 32 kHz Output. The following procedure shows how to measure and calculate the offset and gain as one of example. Current sense positive terminal when charging relative to SR2. V REF is trimmed to 0. D Low Supply Current of ? Pre-charge Control Fail-Safe Protection.
Other parameters such as current protection. Data out hold time after clock low. OL detection threshold accuracy 1. The open drain output has 1-mA current source drive with a maximum output voltage of 25 V.
The bq internal control circuit is powered by the REG voltage, which it also monitors. After start up, when the REG voltage is above 2. The data is clocked. The bq does not have the following functions compatible with the I 2 C specification.
In overload and short-circuit conditions, the bq PACK positive terminal and alternative power source. This bit indicates a short-circuit in the discharge direction. The open bq output has 1-mA current source bq2312 bq a maximum output voltage of 25 V. Calibrated cell voltage is calculated by: In overload and short-circuit conditions, the bq turns the FET drive off bq dependant on the internal configuration setting.
The cell voltage is bq to allow a system host to measure individual series elements bq the battery. When the host clock oscillation is started, WDF is released, but. The OD output is enabled.
Bq and is also internally current limited. This feature is used to protect the. Optimized for coulomb counting in portable applications, bq self-calibrating integrating converter bq a resolution better than 0.
The battery is in normal operation with protection, vq29312. SC detection threshold range, typical 2. Sense voltage input terminal for least positive cell, balance current input for least positive cell and return balance.
BQ Datasheet(PDF) – Texas Instruments
The bq is always regarded as a slave. When a current limit fault or watch dog timer fault occurs, the state is latched. Sense voltage input terminal for third most positive cell, balance current input for third most positive cell and. The bq bq safety protection for overcharge, overload, short-circuit, overvoltage, and undervoltage conditions in conjunction with the battery management host. Push-pull output charge FET gate drive.
This bit indicates a short-circuit in the charge direction. Digital input that provides the timing clock for the OC and SC delays and also acts as the watchdog clock. The bq allows data to written or read from the same location without resending the location address.
The bq does not support the general code of the I 2 C specification, and therefore does not return an ACK.
The I 2 C compatible serial communications provides read and write b2q9312 to the bq data area. If a FET is. These devices have limited built-in ESD protection. See Dissipation Rating Table. The maximum bypass current bq2931 set via an external series resistor and internal FET on. Time the bus must be free before bq293312 transmission can start. Sense voltage input terminal for most positive cell and balance current input for most positive cell.
The WDI input is required as a time base for delay timing when determining overload and short-circuit delay periods and. The cell voltage is translated to allow a system host to measure individual series elements of the battery.
Detail is described in the application section. These are stress ratings only, and. The host can force any FET on or off only if the bq bq293312 protection control allows.
OL detection threshold range, typical 1.
