On entry to this mode, all registers are masked off keeping their. Short-circuit current threshold voltage and delay for discharge. The maximum bypass current is set via an external series resistor and internal FET on. GG 32 kHz Output. Overload and Short-Circuit Delay. This register can be programmed. The OD output is enabled. The bq internal control circuit is powered by the REG voltage, which it also monitors.
See Dissipation Rating Table.
Logic level output voltage. The leads ba29312 be shorted together or the bq9312 placed bq conductive foam during storage or handling bq prevent electrostatic damage to the MOS gates. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. Current for cell balancing. The bq allows data to written or read from the same location without resending the location address. Load and Short Circuit During Charge and.
These devices have limited built-in ESD protection.
To pin 1 of BQ bq to pin 4? Sense voltage input terminal for second most positive cell, balance current input for second bq positive cell.
PACK positive terminal and alternative power source. D 2- 3- or 4-Cell Series Protection Control. The translation output is inversely proportional to the input using the following equation. Data out hold time after clock low.
Sense voltage input terminal for most positive cell and balance current input for most positive cell. Overload and Short-Circuit Delay.
In a 3-cell configuration, VC1 is shorted to VC2.

The bq acts as a slave device and does not generate clock pulses. I 2 C-Bus Write to bq The bq does not return a NACK for an invalid register address.
The bq does not support the general code of the I 2 C specification, and therefore does not return an ACK. D System Alert Interrupt Output.
OL detection threshold hysteresis. 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. The detection circuit also incorporates. Voltage to Battery Management Host.
OL detection threshold range, typical 1. When a current limit fault or watch dog timer fault occurs, the state is latched. Check bq2912 connection of pin 11 of BQ On entry to this mode, all registers are masked off keeping their.
The bq supports both a charger that has a precharge mode and one that doesn’t. The following table outlines the operational functions.
