Toshiba TCK40xG Load Switch ICs
Toshiba TCK40xG Load Switch ICs are 28V high input voltage external FET driver ICs. The TCK40xG ICs offer a slew rate control driver within a small WCSP6E package. These TCK40xG load switch ICs block reverse currents when the switch is turned off using external series FETs. The TCK40xG ICs feature an auto output discharge terminal, charge pump circuit, and inrush current reducing circuit. These load switch ICs operate within a -0.3V to 40V input voltage range and a -40°C to +85°C operating temperature range. The Toshiba TCK40xG Load Switch ICs are suitable for power management selector applications such as battery charging.
