Multicell rechargeable batteries perform better when each cell receives protection from voltage surges and overcurrent events. This block diagram indicates which Littelfuse components offer solutions. In addition to TVS diode arrays and resettable PPTC devices, we offer NTC thermistors and reflowable thermal protectors/battery mini breakers to prevent thermal damage.

Protecting rechargeable single-cell batteries from voltage surges and overcurrent events promotes safety and efficiency. Consult this block diagram to identify Littelfuse components that help achieve those outcomes. Options include TVS diode arrays and resettable PPTC devices. We also make NTC thermistors that sense temperatures and prevent thermal damage to cells and circuits.
