Toshiba Gate Driver + MOSFET for 5V to 24V Line Power MUX

Toshiba Gate Driver + MOSFET for 5V to 24V Line Power MUX is used for power multiplexing, an important feature in applications that require main power supplies to have backup supplies or swapping between charging protocols such as Wireless to USB. Toshiba's TCK42xG series gate driver solution addresses various challenges present in power multiplexing and supports 5V to 24V powerlines.

This gate driver works with a variety of MOSFET configurations. For better power density, common drain MOSFETs are well paired with the TCK42xG series, as it is designed with two gate drive pins. As such, it can be used with common drain MOSFETs like SSM10N954L (12V/2.2mΩ typ. at 3.8V) and SSM6N951L (12V/4.6mΩ). Common drain MOSFET configurations offer 75% space saving compared with a standard 5mm x 6mm MOSFET.

Thanks to its built-in slew rate control and discharge functions, the TCK42xG series offers a 3ms start-up time which helps simplify timing control without additional devices. This series has improved drive and discharge capabilities which help to turn it on and off MOSFET quicker.

TCK42xG series has built-in under-voltage lockout (UVLO) and over-voltage lockout (OVLO) suitable for 5V to 24V power lines. This helps downstream ICs stay protected and within their recommended specs. If overshoot voltage is a concern, adding a Zener diode is another way to protect the device.
