BQ29700DSET

The BQ29700DSET is a Battery Cell Protection Device provides an accurate monitor and trigger threshold for over-current protection during high discharge/charge current operation or battery overcharge conditions. This device provides the protection functions for Li-Ion/Li-Polymer cells and monitors across the external power FETs for protection due to high charge or discharge currents. In addition, there is overcharge and depleted battery monitoring and protection. These features are implemented with low current consumption in NORMAL mode operation.

• VSS - 0.3 to 12V Input voltage range pack+
• CHG and DSG FET drive output
• Voltage sensing across external FETs for overcurrent protection (OCP) is within ±5mV (typical)
• Fault detection for OVP, UVP, OCC, OCD and SCP
• Zero voltage charging for depleted battery
• Fault detection voltage thresholds
• Fault trigger timers
• Fault recovery timers
• 4µA NORMAL Mode ICC, 100nA shutdown Iq (modes of operation without battery charger enabled)
• Green product and no Sb/Br
