TOSHIBA TCK322G,LF

The TCK321G and TCK322G are 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. Switch ON resistance is only 98 mΩ 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 2.0 A per channel. Thus this is suitable for power management selector such as Battery Charge application. This device is available in 0.5 mm pitch small package WCSP16C 1.9 mm×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.
