the HY2120-AB Battery charging IC is designed to protect lithium battery charges with two cells and is suitable for high-precision voltage circuits. overvoltage, overcharging, excessive discharging, and overcurrent are problems that can seriously damage the board or device in sensitive circuits with voltage or lithium battery packs, and therefore battery protection modules are made. the hy2120-ab lithium battery charge protection ic is applicable for lithium-ion and lithium-polymer batteries.

application of HY2120-AB charging protection chip:

  1. rechargeable lithium-ion battery pack with two cells
  2. rechargeable lithium polymer battery pack with two cells

specifications of HY2120-AB Lithium battery charging protection IC:

  1. high accuracy voltage detection circuit
     overcharge detection voltage vcun (n＝1, 2) 4.10 to 4.50v accuracy ±25mv
    overcharge release voltage vcrn (n＝1, 2) 3.90 to 4.30v accuracy ±50mv
     overdischarge detection voltage vdln (n＝1, 2) 2.00 to 3.20v accuracy ±80mv
     overdischarge release voltage vdrn (n＝1, 2) 2.30 to 3.40v accuracy ±100mv
     discharge overcurrent detection voltage (by option)
     charge overcurrent detection voltage (by option) accuracy ±30mv
    short-circuiting detection voltage 1.0v(fixed) accuracy ±0.4v
