Beschreibung
This reference design is a low standby and ship-mode current consumption and high cell voltage accuracy 10s–16s Lithium-ion (Li-ion), LiFePO4 battery pack design. It monitors each cell voltage, pack current, cell and MOSFET temperature with high accuracy and protects the Li-ion, LiFePO4 battery pack against cell overvoltage, cell undervoltage, overtemperature, charge and discharge over current and discharge short-circuit situations. It adopts high-side N-channel MOSFET architecture and has strong driving on and off capability. Through an efficient auxiliary power supply strategy, this reference design achieves 100-μA standby and 10-μA ship mode consumption, saving more energy and allowing longer shipping time and idle time. These features make this reference design highly applicable for e-bike and e-scooter battery pack applications.
Eigenschaften
- Ultra-low current consumption:
- typical 100-μA when in standby mode
- typical 10-μA when in shipping mode
- High cell voltage accuracy without calibrations:
- ±5 mV at 25°C; ±10 mV at 0°C–60°C; ±15 mV at –40°C to 85°C
- Robust battery cell protection, including:
- Primary: cell overvoltage, cell undervoltage, two levels overcurrent discharge, overcurrent charge, discharge short circuit and overtemperature
- Secondary: cell over voltage, cell undervoltage and overtemperature
- Other system protections, including: cell open wire and thermal host watchdog
- Reverse charger and high voltage on PACK side
- High-side N-channel MOSFETs and strong driving capability
Typische Anwendungen
- Battery pack with protection, gauge & external communication, Battery pack: e-bike/e-scooter/light electric vehicle.(LEV)
