New Resettable Overcurrent Circuit Protection for High-Rate-Discharge Li-ion Battery Applications

Useful for high-rate-discharge battery applications at ratings above 30VDC/30A such as cordless power tools, e-bikes, and back-up power supplies.  This technology uses a new hybrid circuit protection approach that combines a bimetal protector in parallel with a polymeric positive temperature coefficient (PPTC) device.  This integrated solution provides resettable overcurrent protection and utilizes the low resistance of the PPTC device to help prevent arcing in the bimetal protector at higher currents, while also heating the bimetal to keep it open and in a latched position.  The device has a 36VDC/100A maximum rating, and a time-to-trip of under five seconds at 100A (at 25°C).  The device’s hold current is 30A, and the initial resistance is under two mOhms.  For more information, please send an email to MyFeedback@dee-inc.com, and be sure to include your contact information.
