ABLIC S-82K3B/K4B Battery Monitoring ICs
ABLIC S-82K3B/K4B Battery Monitoring ICs are designed for secondary protection of lithium-ion rechargeable batteries, incorporating high-accuracy voltage detection circuits and delay circuits. These ICs enable the connection of a 3-serial cell, and the S-82K4B enables the connection of a 4-serial cell. The S-82K3B/K4B ICs provide a wake-up function to prevent the fuse from blowing during battery connection, allowing the lithium battery to be connected in any order. These ICs include a 1.5V to 3.3V VRTC pin output voltage range that can be used as an external Real-Time Clock IC (RTC). The S-82K3B/K4B ICs feature a 2mA maximum VRTC pin output current and a maximum 4µA low current consumption. These battery monitoring ICs are lead-free (Sn 100%) and halogen-free.
