TOKYO–(BUSINESS WIRE)–Sep. 28, 2017
Toshiba Electronic Devices & Storage Corporation today announced the launch of “TCK401G” (active-high) and “TCK402G” (active-low), N-channel MOSFET drivers that support an input voltage of up to 28V, making them suitable for quick-charging and other applications requiring high current supply. Volume shipment of the new MOSFET driver ICs starts today.

The new TCK401G and TCK402G have various built-in functions, including overvoltage protection, inrush current reducing and auto output discharge, but are still housed in the industry-leading small WCSP6E package, measuring 0.8 mm × 1.2 mm × 0.55 mm (typical).
A high-efficiency power supply circuit can be realized by using one of the drivers with an external N-channel MOSFET that has a maximum voltage rating and on-resistance suitable for the target application. For example, the combination of a new MOSFET driver and the low-on-resistance SSM6K513NU MOSFET is suitable for mobile and consumer applications, as it makes it possible to build a 100-W-class power supply circuit in a small space.

 When the mode control input terminal is high state, the external MOSFETs are turned on. When the mode control input terminal is low state, the external MOSFETs are turned off.
 When the mode control input terminal is low state, the external MOSFETs are turned on. When the mode control input terminal is high state, the external MOSFETs are turned off.
