Product Description

The BQ76925PW is a host-controlled Analog Front End IC for 3-, 4-, 5-, or 6-series cell Li-ion and Li-polymer batteries. It allows a host controller to monitor individual cell voltages, pack current and temperature easily. The Host may use this information to determine unsafe or faulty operating conditions such as overvoltage, under- voltage, over temperature, overcurrent, cell imbalance, state of charge and state of health conditions. Cell input voltages are level-shifted, multiplexed, scaled and output for measurement by a Host ADC. A dedicated pin provides a low-drift calibrated reference voltage to enable accurate measurements. The voltage across an external-sense resistor is amplified and output to a Host ADC for both charge and discharge current measurements. Two gain settings enable operation with a variety of sense resistor values over a wide range of pack currents.
Analog interface for host cell measurement
Switchable thermistor bias output for host temperature measurements
Overcurrent comparator with dynamically adjustable threshold
Alerts host to potential overcurrent faults
Wakes up host on load connect
Integrated cell balancing FETs
Individual host control
50mA Per cell balancing current
Supports cell sense-line open wire detection
Low power consumption
Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
