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 range. 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.

? Low ON resistance :

RON = 31 mΩ (typ.) at VIN = 5.0 V, IOUT = -0.15 A

RON = 40 mΩ (typ.) at VIN = 3.3 V, IOUT = -0.15 A

RON = 70 mΩ (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)
