The LC05732ARA is a protection IC for 1-cell lithium-ion secondary batteries with integrated power MOS FET. Also it integrates highly accurate detection circuits and detection delay circuits to prevent batteries from over-charging, over-discharging, over-current discharging and over-current charging. In addition, main system can execute the power-on reset of itself by turning off the charge FET and discharge FET of LC05732ARA for a certain time period, with a reset signal. A battery protection system can be made by only LC05732ARA and few external parts.
Features   Benefits
     
  • Charge-and-discharge power MOSFET are integrated
 
  • Easy design
  • ON resistance (total of charge and discharge ) 4.8 mΩ (typ)
 
  • Low power dissipation
  • Discharge/Charge over-current detection is compensated for temperature dependency of power FET
 
  • Accurate control
  • Highly accurate detection voltage/current at Ta = 25°C, VCC = 3.7 V
    Over-charge detection ±25 mV
    Over-discharge detection ±50 mV
    Charge over-current detection ±0.7 A
    Discharge over-current detection ±0.7 A
 
  • High accurate detection
  • Reset function
    Reset release time : 1 s (typ) [Ta = 25℃]
 
  • More safe operation for embedded battery.
  • 0 V battery charging : “Inhibit”
 
  • Safty operation
  • Auto wake-up function battery charging : “Inhibit”
 
  • Safty operation
Applications   End Products
  • 1-cell Lithium-ion Secondary Batteries Protection
 
  • Smart phones
  • Tablets
  • Wearable devices
