Toshiba TCK12xBG 1A Load Switch ICs

Toshiba TCK12xBG 1A Load Switch ICs are designed for general power management with a slew rate control driver. The TCK12xBG ICs feature ultra-low quiescent current, low switch ON resistance, and a wide 1.0V to 5.5V input operation voltage range. Additionally, the devices provide a quiescent current of 0.08nA and an output current up to 1.0A. Toshiba TCK12xBG 1A Load Switch ICs are housed in a 0.35mm pitch ultra-small WCSP4G package (0.645mm x 0.645mm, t: 0.465mm max.) with a backside coating that protects from external damage. The TCK12xBG ICs are ideal for portable applications that require high-density board assembly and ultra-low power consumption, such as wearables, smartphones, and IoT modules.
