TCK2292xG, TCK2297xG TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCK2292xG, TCK2297xG 2A, 25m Load Switch IC with Slew Rate Control Driver The TCK2292xG and TCK2297xG are load switch ICs for power management with slew rate control driver featuring wide input voltage operation from 1.1 to 5.5 V. Switch ON resistance is only 25 m typical at 5.0 V, -0.5 A load condition and these feature a slew rate control driver. TCK2292xG has output auto-discharge function. Output current type is available on 2 A. These devices are available in 0.4 mm pitch ultra small package WCSP6E (0.8 mm x 1.2 mm, t: 0.55 mm) .Thus they are ideal for portable applications that require high-density board assembly such as cellular phone. Feature Wide input voltage operation: V = 1.1 to 5.5 V IN WCSP6E Low ON resistance: R = 25 m (typ.) at V = 5.0 V, I = -0.5 A Weight: 1 mg (typ.)
