The PolySwitch zeptoSMDC series has been designed to provide robust overcurrent and overvoltage protection on the signal lines for both the lithium ion battery pack ICs and fuel gauge. These PPTCs are for high voltage (13 VDC) applications and are available in the small 0201 surface-mount size. They are intended for smaller mobile and wearable product designs.
Part of the Littelfuse PolySwitch family of resettable overcurrent protection devices, the new series is suited for consumer electronics applications, such as:
- Smartphones
- Notebook PCs, Tablets, and e-Readers
- Wearables (Smartwatches, Fitness Trackers)
- Wireless speakers
- Portable game players
- Portable medical equipment
- Mobile point-of-sale (POS)
Due to the small size of the zeptoSMDC, electronics designers will be able to more easily reduce the overall size of their portable, mobile, and wearable products while providing improved levels of protection for the battery fuel gauge and battery management IC, according to the company.
The zeptoSMDC series PPTC offers the following key benefits:
- Saves PCB space due to small 0201 size footprint.
- Helps protect battery monitor IC from electrical over-stress.
- Resets to normal operation after fault is cleared.
