ISL9208
ISL9208 is Multi-Cell Li-ion Battery Pack OCP/Analog Front End manufactured by Renesas.
Features
- Software selectable overcurrent protection levels and variable protect detection 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 override 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 discharge FET.
- Single N-Channel FET for discharge, with separate, optional (smaller) back-to-back N-channel FETs for charge.
