TCK305G TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCK305G 28 V, Single input Single Output Load Switch IC with Over Voltage Protection The TCK30 series are 28 V high input voltage Single Inputs-Single Output load switch ICs. It has Over Voltage Protection function featuring low switch ON resistance, high output current and wide input voltage operation. Switch ON resistance is only 73 m at 4.5 V, - 1.0 A load conditions. And these feature 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 3 A. Thus this is suitable for power management such as Battery Charge application. WCSP9 This device is available in 0.5mm pitch ultra small package WCSP9 Weight : 3.5 mg ( Typ.) (1.5 mm x 1.5 mm, t: 0.5 mm (Typ.)).Thus this devices is ideal for portable applications that require high-density board assembly such as cellular phone. Feature High input voltage: VIN (Max) = 28 V High output current: I (DC) = 3.0 A OUT Low ON resistance : R = 73 m (Typ.) at V = 4.5 V, I = - 1.0 A ON IN OUT Over Voltage Lockout : 10.5 V (Typ.) Under Voltage Lockout: 2.9 V (Typ.)
