Battery Packs
From tactile on–off switches to thermal cutoff devices that protect cells, Littelfuse provides solutions for cordless power tool battery packs. A block diagram shows other components we offer to protect and bolster the performance of small rechargeable Li-ion batteries. Available parts include resettable fuses and TVS diode arrays for, respectively, overcurrent and overvoltage protection.
BLDC Motors
MOSFETs and NTC thermistors from Littelfuse help optimize the performance of brushless dc (BLDC) motors in cordless power tools. A block diagram shows how our solid state switches and temperature sensors fit into BLDC motor circuitry. We also provide high-voltage fuses for overcurrent protection, TVS diode arrays for overvoltage protection, and reed switches to engage and disconnect components.
Chargers
Cordless power tool battery chargers require efficient rectifiers and reliable overcurrent and overvoltage protection devices. A block diagram shows which MOSFET ac–dc converters, TVS diode arrays, metal oxide varistors, Schottky diodes, and miniature fuses made by Littelfuse that battery charger designers can use.
Sealed Tactile Switches Power up Reliability
Success Story
Sealed Tactile Switches Power up Reliability
Sealed Tactile Switches Power up Reliability
A power tool manufacturer needed a durable, compact switch to activate the battery-level indicator on its next-gen cordless drill. Standard push buttons failed under daily wear and job site exposure to dust and moisture. After testing multiple options, the engineering team chose a Littelfuse sealed tactile switch rated for 1 million cycles and IP67 protection. The result? Improved assembly accuracy, enhanced user experience—even with gloves—and long-term switch reliability in harsh environments. The product launched on time with no redesigns.
