Features for the BQ77307

  • Primary or secondary voltage, current, and temperature protection for 2-series to 7-series cells with an autonomous recovery option
  • Voltage protection:
    • Cell overvoltage (COV): 0 V–5.5 V in 1-mV steps, ±4-mV accuracy
    • Cell undervoltage (CUV): 0 V–5.5 V in 1-mV steps, ±4-mV accuracy
  • Current protection:
    • Short circuit in discharge (SCD): 10 mV–500 mV, varying steps
    • Overcurrent in charge (OCC): 3 mV–123 mV, 2-mV steps
    • Overcurrent in discharge 1 and 2 (OCD1 and OCD2): 4 mV–200 mV, 2-mV steps
  • Temperature protection using external NTC thermistor:
    • Overtemperature in charge and discharge (OTC and OTD)
    • Undertemperature in charge and discharge (UTC and UTD)
    • Internal die overtemperature
  • Integrated low-side drivers for NFET protection with an optional autonomous recovery
  • Low power operation:
    • NORMAL mode, both FETs enabled: 8 µA
    • NORMAL mode, FETs disabled: 5 µA
    • SHUTDOWN Mode: < 1 µA
  • High voltage tolerance of 45 V on cell connect and select additional pins
  • Integrated one-time-programmable (OTP) memory for device settings, programmed by TI
  • Programmable interrupt for host processor, status information available through I 2C
  • 400-kHz I 2C serial communications with optional CRC support

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
