Toshiba TCK207AN Load Switch IC offers a 0.75V ultra-low voltage with a slew rate control driver and reverses the current blocking (SW OFF state) function. The TCK207AN is ideal for power management and portable applications that require high-density board assembly such as SSD, HDD, cellular phone.

The Toshiba TCK207AN Load Switch IC supports a switch ON resistance of only 21.5mΩ (typ.) at 0.75V, -1.5A condition, and output current is available up to 2.0A (DC).

The TCK207AN is housed in a DFN4A (1.2mm x 1.2mm, t:0.38mm) ultra-small package.
