Toshiba TCK3xx Single Output Power Multiplexer ICs are single output multiplexer load switch ICs with overvoltage protection and low switch ON resistance. Each of these devices also has high output current and wide input voltage operation from 2.3 up to 36V (28V for TCK302 & TCK303). These have a Switch ON resistance as low as 73mΩ (TCK302 & TCK303) or 98mΩ (TCK323) at VIN = 4.5V, - 1.0A load conditions. They feature a slew rate control driver, thermal shutdown and flag function (TCK302 & TCK303 only). They can also block reverse current if a switch is turned off. The output current is 2.0A (TCK323) or 3.0A (TCK302, TCK303) per channel. This makes these devices suitable as a power management selector for a battery charging application.
