TCK106G/TCK107G/TCK108G TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCK106G, TCK107G, TCK108G 1.0 A Load Switch IC with Slew Rate Control Driver in Ultra Small Package The TCK106G, TCK107G and TCK108G are load switch ICs for a general power management with slew rate control driver, featuring low switch ON resistance and wide input voltage operation from 1.1 to 5.5 V. Switch ON resistance is only 49 m typical at 5.0 V, 500 mA condition and output current is available on 1.0 A. TCK107G and TCK108G feature output auto-discharge function. These devices are available in 0.4 mm pitch ultra small package WCSP4 (0.79 mm x 0.79 mm, t: 0.5 mm) .Thus this devices is ideal WCSP4 for portable applications that require high-density board assembly Weight: 0.7 mg (typ.) such as cellular phone. Feature Wide input voltage operation: V = 1.1 to 5.5 V IN High output current: I = 1.0 A OUT Low ON resistance : R = 49 m (typ.) at V = 5.0 V, 500 mA ON IN R = 57 m (typ.) at V = 3.3 V, 500 mA ON IN R = 83 m (typ.) at V = 1.8 V, 500 mA ON IN R = 143 m (typ.) at V = 1.2 V, 200 mA ON IN R = 176 m (typ.) at V = 1.1 V, 200 mA ON IN Built in Slew rate control driver Built in Auto-discharge (TCK107G and TCK108G) Active High and Pull down connection between CONTROL and GND (TCK106G and TCK107G) Active Low (TCK108G) Ultra small package : WCSP4 (0.79 mm x 0.79 mm, t: 0.5 mm) Pin Assignment(Top view) Top marking V CONTROL IN (A2) (B2) 6K: TCK106G 7K: TCK107G 8K: TCK108G V GND OUT Index (A1) (B1) Start of commercial production 2013-02 1 2014-03-01 TCK106G/TCK107G/TCK108G Absolute Maximum Ratings (Ta = 25C) Characteristics Symbol Rating Unit Input voltage V 6.0 V IN Control voltage V -0.3 to 6.0 V CT Output voltage V -0.3 to V +0.3 V OUT IN Output current I DC 1.0 A OUT Power dissipation P 800 (Note 1) mW D Operating temperature range T 40 to 85 C opr Junction temeperature Tj 150 C Storage temperature T 55 to 150 C stg 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 and the operating ranges. 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).
