“TCK401G” (active-high[1]) and “TCK402G” (active-low[2]) are N-channel MOSFET drivers that support an input voltage of up to 28 V, making them suitable for quick-charging and other applications requiring high current supply.
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[3] small WCSP6E package, measuring 0.8×1.2×0.55 mm (typ.).
A high-efficiency power supply circuit can be realized by using new drivers with an external N-channel MOSFET that has a maximum voltage rating and On-resistance which are suitable for the target application. For example, the combination of a new MOSFET driver and the low-On-resistance MOSFET SSM6K513NU 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.
Notes:
[1] 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.
[2] 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.
