負載開關IC

Product List

負載開關IC的參數檢索

負載開關IC是採用CMOS工藝加工而成的一種電源IC,該工藝包括一個輸出電晶體和一個輸出驅動器。負載開關IC相比於由分立器件組成的IC具有更小的體積。另外,負載開關IC具有低壓運轉、低導通電阻和低電流消耗的特點,而且可以提供附加的功能。其超小型封裝中的底座面積小於1mm2,所以東芝的負載開關IC特別適合於對空間要求非常苛刻的可擕式設備應用場合。

特徵

1. Ultra-small packages
Saves board space due to the use of WCSP packages

2. Low on-resistance
Available in many variants with low on-resistance, including those with low on-resistance of less than 10 mΩ, due to the use of small-geometry process and voltage-boosting technology

3. Rich functions
Incorporates various functions such as inrush current limiting, reverse-current protection, overcurrent protection, thermal shutdown and automatic output discharge that are complicated to build with discrete components

4. Wide operating voltage range
The ultra-low-voltage series operates at 0.75 V while the general-purpose series operates at 1.1 to 5.5 V.

5. Product performance guarantee
Standardized on-resistance, leakage and other temperature characteristics that are difficult to achieve with discrete MOSFETs

Features of the TCK Series

特徵

TCK10xG Series
The TCK10xG Series features a wide operating voltage range of 1.1 to 5.5 V and low current consumption. It is available with a maximum output current of up to 1 A and ideal for applications requiring power saving at light loads.
The TCK106G, TCK107G and TCK108G consume only 0.2 μA (max) during active operation (VIN = 5.5 V, IOUT = 0 mA, Ta = -40 to 85°C).
Load switch ICs with reverse-current protection are also available.

TCK11xG Series
The TCK11xG Series features a wide operating voltage range of 1.1 to 5.5 V and ultra-low on-resistance. The TCK11xG Series provides an on-resistance of approximately 8 mΩ, despite its small size and incorporates reverse-current protection and thermal shutdown. It can be used for diverse applications such as driver switches for the battery line and low-voltage switches rated at 1 A or higher.

TCK20xG Series
The TCK20xG Series features ultra-low-voltage operation as low as 0.75 V and low on-resistance. It also provides an on-resistance of approximately 18 mΩ despite using the ultra-small WCSP4C package and incorporates reverse-current protection. Those housed in the general-purpose SMV (SOT-25) package are under development.
