TCK104G,TCK105G 2014-03-01 1 TOSHIBA CMOS Linear Integrated Ci rcuit 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-dischar ge 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.

TCK104G,TCK105G 2014-03-01 6 Application Note 1. Application circuit example (top view) The figure below shows the recommended configuration for TCK104G and TCK105G 1) Input capacitor An input capacitor(C IN) is not necessary for the guaranteed operation of TCK104G and TCK105G. However, it is recommended to use input capacitors to reduce voltage drop due to sharp changes in output current and also for improved stability of the powe r supply. When used, place C IN as close to V IN pin to improve stability of the power supply. Also, due to the C IN selected, VIN < V OUT may occur, causing a reverse current to flow through the body diode of the pass-through p-ch MOSFET of the load switch IC. In this case, a higher value for C IN as compared to CL is recommended. 2) Output capacitor An output capacitor (C OUT) is not necessary for the guaranteed operation of TCK104G and TCK105G. However, there is a possibility of overshoot or undershoot caused by output load transient response, board layout and parasitic components of load switch IC. In this case, an output capacitor with C OUT more than 0.1μ F us recommended. 3) Control pin A control pins for TCK104G and TCK105G are both Active High, which controls both the pass-through p-ch MOSFET and the discharge n-ch MOSFET, operated by the control voltage and Schmitt trigger. When the control voltage level is High, p-ch MOSFET is ON state and n- ch MOSFET is OFF state. W hen control voltage level is Low, and the state of the MOSFETs is reversed. Also, pull down resistance equivalent to a few MΩ is connected between CONTROL and GND, thus the lo ad switch IC is in OFF state even when CONTROL pin is OPEN. In addition, CONTROL pin has a tolerant f unction such that it can be used even if the control voltage is higher than the input voltage.

[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 condit ion. Furthermore, Toshiba recommend inserting failsafe system into the design. 200 400 600 800 1000 -40 0 40 80 120 Power Dissipation PD (mW) Ambient Temperature Ta (℃) PD -T a
