Power Switch Hi Side 1A 4-Pin WCSP

The TCK108AG is load switch ICs for a general power management with slew rate control driver, featuring low ON resistance and wide input voltage operation from 1.1 to 5.5 V. ON resistance is only 34 m? typical at 5.0 V, -0.5 A condition and output current is available on 1.0 A. TCK108AG feature output auto-discharge function. These devices are available in 0.4 mm pitch ultra small package WCSP4D (0.79 mm x 0.79 mm, t: 0.55 mm) .Thus this devices is ideal for portable applications that require high-density board assembly such as cellular phone.

• Low ON resistance :
  • Ron = 34 m? (typ.) at Vin = 5.0 V, -0.5 A
  • Ron = 42 m? (typ.) at Vin = 3.3 V, -0.5 A
  • Ron = 71 m? (typ.) at Vin = 1.8 V, -0.5 A
  • Ron = 139 m? (typ.) at Vin = 1.2 V, -0.2 A
  • Ron = 176 m? (typ.) at Vin = 1.1 V, -0.2 A
• Low Quiescent current Iq = 110 nA (typ.) at Vin = 5.5 V, 0 mA
