TCK323G TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCK323G 36 V, Dual Inputs Single Output Power Multiplexer IC with Over Voltage Protection The TCK323G is 36 V high input voltage Dual Inputs Single Output multiplexer load switch ICs. It has Over Voltage Protection featuring low switch ON resistance, high output current and wide input voltage operation from 2.3 to 36V. Switch ON resistance is only 98 m (typ.) at V = 4.5 V, - 1.0 A load conditions. And these IN 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 2.0 A per channel. Thus this is suitable for power management selector such as Battery Charge application. WCSP16C This device is available in 0.5 mm pitch small package WCSP16C Weight : 3.9 mg ( typ.) (1.9 mm x 1.9 mm, t: 0.5 mm (typ.)).Thus this devices is ideal for portable applications that require high-density board assembly such as mobile phone. Feature High output current: I (DC) = 2 A, per channel OUT Low ON resistance : R = 98 m (typ.) at V = 4.5 V, - 1.0 A, per channel ON IN Wide input voltage operation: V = 2.3 to 36 V IN Over Voltage Lockout : 15.0 V (typ.) Under Voltage Lockout: 2.9V (typ.) Reverse current blocking per channel(SW OFF state) Inrush current reducing circuit.
