Logic Fuse Protection for Li-Ion Battery Packs in High-Current Applications

The Schott D6SC battery logic fuse, from ATC Semitec, provides valuable overcharge AND over-current protection, making them ideal for the protection of Li-Ion battery packs. This miniature surface mount fuse has an ultra-thin fuse body (<1mm thin, 3 x 4mm land area) and is now available with ratings up to 60 Amps.

Safe operation is the top priority for Li-Ion batteries. While conventional current fuses only offer protection against high current incidents, the SCHOTT SEFUSE® D6S range of Battery Logic Fuses provide additional protection against overcharging.

These miniature surface mount battery logic fuses reliably cut off in case of overcurrent during discharge or overcharging. Additionally, these fuses will help prevent fires caused by overheating. 

Excessive discharge currents will blow the fuse in a conventional manner. If there is an overcharge condition, then the D6S’s built-in heater is triggered by the FET linked to the battery’s secondary protection IC.  This integral heater then helps to blow the fuse circuit and protects the Li-ion battery.

Suitable for space limiting applications these ultra -thin SMDs are available in packages as small as 0.7mm x 1.8mm x 2.7mm.

Available from ATC Semitec, these SEFUSE® Battery Logic Fuses enable improved Li-ion battery safety in applications up to 60 Amps. Applications include battery packs for gardening/power tools, cordless, robotic household appliances, energy storage systems, e-bikes, e-scooters and e-motorcycles.
