TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCK22xxxG, TCK2065G, TCK1024G
Load Switch IC with Over current limited function
The TCK22xxxG, TCK2065G and TCK1024G are Load Switch ICs for
power management with Over Current Limited function featuring low
switch on resistance, ultra low quiescent current, high output current and
wide input voltage operation. Typical switch ON resistance is only 31 mΩ
at VIN = 5.0 V, IOUT = -0.15 A load conditions. And these feature a thermal
shut down function 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). So these devices are ideal for
portable applications that require high-density board assembly such as
cellular phone.
Feature
Over current limit function
ICL = 400/740/1110/1540 mA (Option)
Thermal shutdown function
Inrush current reduction
Output auto-discharge function
True reverse current blocking function(Option)
Under voltage lockout function(Option)
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
Low quiescent current: IQ = 25 μA (typ.) at VIN = 5.5 V, IOUT = 0 mA
Pull down connection between CONTROL and GND
Ultra small package : WCSP6E (0.8 mm x 1.2 mm, t: 0.55 mm)
