TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCK104G, TCK105G
Load Switch IC with Current Limit function
The TCK104G and TCK105G are load switch ICs for power
management with slew rate control driver and current limit
function featuring wide input voltage operation from 1.1 to 5.5 V.
Switch ON resistance is only 50 mΩ typical at 5.0V, -700mA load
condition and these feature a slew rate control driver, thermal
shutdown and output auto-discharge function. Output current
type is available on -500mA, and -800mA. Thus it is easy to
select devices and helpful for the design.
This device is available in 0.4 mm pitch ultra small package
WCSP6B (0.8 mm x 1.2 mm, t: 0.64 mm (max)) .Thus this
devices is ideal for portable applications that require high-density
board assembly such as cellular phone.
WCSP6B
Weight: 1 mg (typ.)
Feature
• Wide input voltage operation: VIN = 1.1 to 5.5 V
• Low ON resistance :
RON = 50 mΩ (typ.) at VIN = 5.0 V, -700 mA
RON = 55 mΩ (typ.) at VIN = 3.3 V, -700 mA
RON = 75 mΩ (typ.) at VIN = 1.8 V, -700 mA
RON = 140 mΩ (typ.) at VIN = 1.2 V, -700 mA
• Low Quiescent Current: IQ = 20 μA (typ.) at IOUT = 0 mA
• Low standby current: IQ(OFF) = 0.1 μA (typ.) at OFF state
• Current limit function
• Inrush current reducing circuit
• Thermal Shutdown function
• Auto-discharge
• Pull down connection between CONTROL and GND
• Ultra small package : WCSP6B (0.8mm x 1.2mm, t: 0.64mm(max))

[The Board Condition]
Board material: Glass epoxy (FR4)
Board dimension: 40mm x 40mm (both sides of board),t=1.8mm
Metal pattern ratio: a surface approximately 50%, the reverse side approximately 50%
Through hole: diameter 0.5mm x 28

Please allow sufficient margin when designing a board pattern to fit the expected power dissipation. Also take into
consideration the ambient temperature, input voltage, output current etc and applying the appropriate derating for
allowable power dissipation during operation.
3. Current limit and Thermal shut down function
Current limit and Thermal shutdown function are designed in these products, but these does not assure for the
suppression of uprising device operation. In use of these products, please read through and understand dissipation
idea for absolute maximum ratings from the above mention or our ‘Semiconductor Reliability Handbook’. Then use
these products under absolute maximum ratings in any condition. Furthermore, Toshiba recommend inserting failsafe
system into the design.
