TCK301G/TCK302G/TCK303G TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCK301G, TCK302G, TCK303G 28 V, Single input Single Output Load Switch IC with Over Voltage Protection The TCK30 series are 28 V high input voltage Single InputsSingle 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 : 6.6 V, 10.5 V, and 15.5 V (Typ.) Under Voltage Lockout: 2.9 V (Typ.)
