TCK305G,LF(S

TCK305G,LF(S is a TCK30 series are 28V high input voltage single inputs-single output load switch IC. It has over voltage protection function featuring low switch ON resistance, high output current and wide input voltage operation. And this features a slew rate control driver, thermal shutdown and flag function. Also it can block reverse current if switch turned off. Output current is available up to 3A. Thus, this is suitable for power management such as battery charge application. This device is available in 0.5mm pitch ultra small package WCSP9.Thus this device is ideal for portable applications that require high-density board assembly such as cellular phone.
