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 x 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.

Feature
 True Reverse Current Blocking
 Thermal Shutdown function
 Output auto-discharge (Option)
