TCK128BG
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCK128BG
0.08 nA Ultra small IQ 1.0 A Load Switch IC in Ultra Small Package
TCK128BG is load switch IC for a general power management with slew
rate control driver, featuring super low quiescent current, low switch ON
resistance and wide input operation voltage range from 1.0 to 5.5 V.
Quiescent current is only 0.08 nA and output current is available up to
1.0 A. TCK128BG also feature output auto-discharge function.
This device is available in 0.35 mm pitch ultra small package WCSP4G
(0.645 mm x 0.645 mm, t: 0.465 mm max.) with back side coating that
protect from external damage.
Thus this device is ideal for portable applications that require high-density
board assembly and ultra low power consumption such as wearables,
smartphones, and IoT modules. WCSP4G
