TOSHIBA TCK22912G,LF

The TCK2291xG series is Load Switch ICs for power management with True Reverse Current Blocking and Thermal Shutdown function featuring low switch on resistance, ultra low quiescent current, high output current and wide input operating voltage range of 1.1 to 5.5 V. Switch ON resistance is only 31 mΩ at 5.0 V, -0.15 A load conditions and output current is available on 2.0 A. And these feature a slew rate control driver and output auto-discharge function. These devices are available in 0.4 mm pitch ultra small package WCSP6E (0.8 mm×1.2 mm, t: 0.55 mm). Thus these devices are ideal for portable applications that require high-density board assembly such as cellular phone.
