ABLIC Launches S-82K3/K4 Secondary Protection ICs

ABLIC, a group company of MinebeaMitsumi Inc. today launched the S-82K3/K4 Series of 3-serial to 4-serial cell secondary protection ICs with the industry’s first wake-up function that allows the battery to be connected in any order and a constant voltage output pin for driving an external RTC (real-time clock).
The S-82K3/K4 Series of 3-serial to 4-serial cell secondary protection ICs launched today have the following three features:

  • Wake-up function that monitors whether all batteries have been connected regardless of the order the battery and the protection circuit has been connected, ensuring that a blown fuse signal for the protection fuse is not output until all batteries have been connected. It allows the protection circuit and the battery to be connected in any order without blowing the fuse, which simplifies work procedures during battery assembly.
  • Internal constant-voltage output circuit that can supply power to an external RTC.
  • Industry-leading low current consumption of 4µA max. despite having an overcharge detection voltage accuracy of ±15mV, which places them in the industry’s top class, and high performance constant voltage output circuit.

ABLIC will continue leveraging our technology and knowhow to develop lithium-ion battery protection ICs with even greater accuracy and higher performance to roll out products for applications in a wide variety of fields.
