TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCK206G, TCK207G, TCK208G
0.75 V, 2A Load Switch IC with Reverse Current Blocking in Ultra Small Package
The TCK206G, TCK207G and TCK208G are 0.75 V ultra low voltage load
switch ICs for a power management with slew rate control driver and reverse
current blocking(SW OFF state) function.
Switch ON resistance is only 18.4 m(typ.) at 0.75 V, -1.5 A condition and
output current is available up to 2.0 A (DC). TCK207G and TCK208G feature
output auto-discharge function.
These devices are available in 0.5 mm pitch ultra small package WCSP4C
(0.9 mm x 0.9 mm, t: 0.5 mm (typ.)). Thus, these devices are ideal for
portable applications that require high-density board assembly such as
cellular phone.
Weight : 0.9 mg ( typ.)
Feature
Low input voltage operation: VIN = 0.75 to 3.6 V
High output current: IOUT (DC) = 2.0 A
Low ON resistance :
RON = 18.1 m(typ.) at VIN = 3.3 V, -1.5 A
RON = 18.2 m(typ.) at VIN = 1.2 V, -1.5 A
RON = 18.4 m(typ.) at VIN = 0.75 V, -1.5 A
Built in Slew rate control driver
Built in Reverse current blocking(SW OFF state)
Built in Auto-discharge (TCK207G and TCK208G)
Active High and Pull down connection between CONTROL and GND (TCK206G and TCK207G)
Active Low (TCK208G)
Ultra small package : WCSP4C (0.9 mm x 0.9 mm, t: 0.5 mm)

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.).
Note1: 100 μs pulse, 2% duty cycle
Note2: Rating at mounting on a board
(Glass epoxy(FR4) board dimension : 40mm x 40mm, both sides of board
Metal pattern ratio : a surface approximately 50%, the reverse side approximately 50%
Through hole : diameter 0.5mm x 28)
