401 TCK401G, TCK402G TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCK401G, TCK402G External FET Driver IC The TCK401G and TCK402G are 28 V high input voltage External FET driver ICs. They have wide input voltage range. And they feature a slew rate control driver with small package WCSP6E (0.8 mm x 1.2 mm, t: 0.55 mm). Also they can block reverse current if switch turned off by using external series FET. Thus they are suitable for power management selector such as Battery Charge application Feature Weight: 1 mg(typ.) High maximum input voltage: V = 40 V IN max Wide input voltage range: V = 2.7 to 28 V IN Auto output discharge Charge pump circuit Inrush current reducing circuit.
