Cordless Power Tool Solution

To Realize Compact, Light, Easy-to-Carry and Easy-to-Work with Long Time Operation
Cordless Power Tool Solution

Various types of power tools are marketed for a wide range of applications from household to professional use. Recently, the adoption of high-capacity lithium-ion batteries leads to a shift to cordless types that are compact, light, easy-to-carry and easy-to-work with not only for household use but also for professional use such as hammer drills, impact wrenches, nailers, staplers, and round saws. The cability of cordless power tools to run longer time operation with a single charge is one of the major qualities for users when choosing the goods. Toshiba's lineup of MOSFET, motor control drivers, photocouplers, and other products that use the newest technologies helps you make efficient use of limited battery capacities.

Three-phase Brushless Motor Drive

Example of Three-phase Brushless Motor Drive Block Diagram
Example of Three-phase Brushless Motor Drive Block Diagram

Three-phase brushless motor drive circuits with inverter control can be easily realized by using the motor driver TC78B016FTG. In addition, the large-capacity brushless motor drive can be achieved by using TB6634FNG which is an external three-phase brushless motor driver. For TB6634FNG, we recommend a MOSFET, which are TPWR8004PL and TPHR8504PL, with low on-resistance and high heat dissipation efficiency. Combined with TB6634FNG offers a low-heat, low-power solution. In addition, each product is provided in a small molded package, enabling a reduction in the mounting area.

By using an ultra-low-noise op-amp TC75S67TU, you can detect equipment errors and protect the battery by combining the current monitoring circuit of the system power supply and the temperature sensor. In addition, the use of the LDO regulator: TAR5SB series for the system power supply enables the reduction of noise coming from motor drive and enable a highly noise-resistant power supply circuit that is indispensable for stable system operation.

The set with low heat generation and low power consumption can be realized by using MOSFET with high dissipation efficiency and low on-resistance as a driver.

Power Supply for Battery Charging

Example of Power Supply for Battery Charging Block Diagram

Since high withstand voltage and low on-resistance performance are required for MOSFET used in PFC circuits of AC-DC power supplies, select products with the optimum rating according to the required specifications of the application such as TK17A80W.

eFuse IC is a type of electronic fuse that can be used repeatedly by applying electronic circuitry. Use of TCKE805 on the battery power line protects the system in unexpected power fault conditions.

By using a photocoupler such as a TLP385 for the voltage feedback circuit, the feedback signal can be transmitted while electrically isolating the primary and secondary sides by optical coupling, thus improving the operational reliability of the system.

In addition, it is essential to observe the safety standards established in each country. Toshiba Photocouplers have been approved by UL1577VDE:EN60747-5-5, EN62368-1 and other organizations.

MOSFET with high VDSS and low on-resistance is suitable for the PFC circuit of the AC-DC power supply. The DTMOS series has a super junction structure capable of reducing the resistance of the drift layer, and achieve both low on-resistance and high-speed switching.
