TCK207AN
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCK207AN
0.75 V, 2A Load Switch IC with Reverse Current Blocking in Ultra Small Package
TCK207AN is 0.75 V ultra-low voltage load switch IC for a power
management with slew rate control driver and reverse current blocking (SW
OFF state) function.
Switch ON resistance is only 21.5 m(typ.) at 0.75 V, -1.5 A condition and
output current is available up to 2.0 A (DC). TCK207AN features output auto-
discharge function.
This device is available in ultra-small package DFN4A (1.2 mm x 1.2 mm, t:
0.38 mm) .Thus this device is ideal for portable applications that require high-
density board assembly such as SSD, HDD, cellular phone.

Note : Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant
change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating
conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the
appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling
Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated
failure rate, etc.).
