Current sense positive terminal when charging relative to SR2. D Low Supply Current of ? This bit indicates a short-circuit in the charge direction. Supply voltage ba29312 PACK.
I 2 C-Bus Read from bq The bq analog front-end AFE protection Bq is used to maximize functionality and safety and minimize component count b29312 cost in smart battery circuits. Logic level input voltage.
This provides a range. The bq is a 2- 3- or 4-cell lithium-ion battery pack. Other parameters such as current protection. On entry to this mode, all registers are masked off keeping their. Bq is designed to bq29321 bq the bq AFE protection IC to maximize functionality and safety and minimize component count and cost in smart battery circuits. OL detection threshold range, typical 1. SCLK pulse width high. The output voltage includes the scale factor error and bq299312 and is represented by: The bq bq not have the following functions compatible with the I 2 C specification.
The bq supports both a charger that has a precharge mode and one that doesn’t. Setup time for STOP condition. To clear these faults, bbq29312 from 0, set 1. D Medical and Test Equipment. Precharge and 0 V Charging–Theory of Operation.
BQ Datasheet(PDF) – Texas Instruments
Short-circuit current threshold voltage and delay for discharge. This register can be programmed. Lead temperature soldering, 10 sec. When the host clock oscillation is started, WDF is released, but.
The bq does not return a NACK for an invalid register address. See Dissipation Rating Table.
TOUT pass-element series resistance. Single Supply ; Settling Time: Extend CELL output filter.
The bq is completely shut down as in the sleep mode. Provides thermistor bias current. These devices have limited built-in ESD protection. SC detection threshold program step. TOUT pass-element series resistance.
Calibrated cell voltage is calculated by: There are a couple of method by calibration circumstance. The cell balance control allows a small bypass path to be controlled for any one series element. Push-pull output bq299312 FET gate drive. How bq recognize if i can reset BQ or not? Overload and Short-Circuit Delay. D System Alert Interrupt Output. The short-circuit threshold can be programmed from mV to mV in mV steps with the default.
V REF is trimmed to 0. SC detection threshold accuracy 2. OL detection b29312 program step.
The leads should be shorted together or the device placed in conductive foam during. PACK positive terminal and nq29312 power source. Output voltage, charge and discharge. Short-circuit current threshold voltage and delay for charge.
Logic level output voltage. D Programmable Threshold and Delay for Over. F and is also internally current limited. OC and SC protection: Sense voltage input terminal for second most positive cell, balance current input for second bq positive cell. The bq provides safety protection for overcharge.
OL detection threshold accuracy 1.
