TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCK2291xG
TCK2291xG
2A Load Switch IC with True Reverse Current Blocking
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 voltage operation from 1.1 to 5.5 V. Switch
ON resistance is only 31 mat 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.
This device is available in 0.4 mm pitch ultra small package WCSP6E
(0.8 mm x 1.2 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 = 31 m(typ.) at VIN = 5.0 V, IOUT = -0.15 A
RON = 40 m(typ.) at VIN = 3.3 V, IOUT = -0.15 A
RON = 70 m(typ.) at VIN = 1.8 V, IOUT = -0.15 A
RON = 141 m(typ.) at VIN = 1.2 V, IOUT = -0.15 A
Low Quiescent Current: IQ = 11 μA (typ.) at IOUT = 0 mA
Low standby current: IQ(OFF) = 0.6 μA (typ.) at OFF state
Inrush current reduction circuitt
Pull down connection between Control and GND(Option)
Ultra small package : WCSP6E (0.8 mm x 1.2 mm, t: 0.55 mm)
