TCK3xx Single Output Power Multiplexer ICs

Toshiba TCK3xx Single Output Power Multiplexer ICs are single output multiplexer load switch ICs with overvoltage protection and low switch ON-resistance. These devices also have high output current and wide input voltage operation from 2.3 to 36V (28V for TCK302 and TCK303). These have a Switch ON-resistance as low as 73mΩ (TCK302 and TCK303) or 98mΩ (TCK323) at VIN = 4.5V, - 1.0A load conditions.
