ISL9217
ISL9217 is 8 to 12 Cell Li-Ion Battery Overcurrent Protection and Analog Front End Chip Set manufactured by Renesas.
- Part of the ISL9216 comparator family.
- Part of the ISL9216 comparator family.
Features
- Software selectable overcurrent protection levels and variable protect detection/release times
- 4 Discharge overcurrent thresholds
- 4 Short circuit thresholds
- 4 Charge overcurrent thresholds
- 8 Overcurrent delay times (Charge)
- 8 Overcurrent delay times (Discharge)
- 2 Short circuit delay times (Discharge)
- Automatic FET turn-off and cell balance disable on reaching external (battery) or internal (IC) temperature limit
- Automatic over-ride of cell balance on reaching internal (IC) temperature limit
- Fast short circuit pack shutdown
- Can use current sense resistor, FET r DS(ON), or Sense FET for overcurrent detection
- Four battery backed software controlled flags
- Allows three different FET controls:
- Back-to-back N-Channel FETs for charge and discharge control
- Single N-Channel FET for discharge control
- N-Channel FET for discharge, with separate, optional (smaller) back-to-back FET for...
