Cordless Power Tools

ABLIC コードレス電動工具に最適なIC

Cordless power tools are widely used both in the home and the workplace. Cordless power tools must be tough, compact and light weight, and also need long-lasting batteries. Safe operation and safety functions are also indispensable. ABLIC supplies a wide range of ICs that are ideal for electric screwdrivers and other cordless power tools. We provide a full line of voltage regulators suitable for powering motor control microcontrollers, Hall effect ICs for detecting motor rotation and rotation direction, Rail-to-Rail input CMOS operational amplifiers for calculating current. These ICs all feature low current consumption and compact size to contribute to long life of cordless power tool batteries and compact tool size. Our lineup also includes a great number of battery monitoring ICs for improving the safety of lithium-ion battery packs and secondary protection ICs that provide dual overcharge protection for even greater safety. They also ensure that applications using them comply with UL, IEC and other safety standards. ABLIC supplies a comprehensive range of ICs, from motor control through to battery monitoring that are all specially designed for electric power tools.

Major Features

S-8245/55 Battery Protection IC

Temperature protection Power saving function Secondary protection IC

4-temperature monitoringTemperature protection
A single connection of an NTC thermistor to the temperature detector pin enables 4-temperature monitoring.

Power-savingPower-saving function
An external signal allows you to switch to low current consumption mode (0.1uA max.). During battery pack shipment, this function prevents consumption of battery capacity by dark current.

Secondary ProtectionSecondary protection IC
Overcharge protection by the secondary protection IC adds a dual layer of protection to enable the design of safer battery packs. This function helps products meet power tool safety standards.

S-1009 Product information/datasheet

S-1410/1 Watchdog Timer Microcontroller monitoring

This timer monitors microcontroller operation by checking the edge that is regularly input to the microcontroller. Two modes are provided: Timeout mode that determines an error has occurred only when the interval between edge inputs is too long and Window mode that determines an error has occurred also when the interval between edge inputs is too short.
