Toshiba TCK22xG/TCK1024G Load Switch ICs

Toshiba TCK1024G Load Switch ICs feature overcurrent limit function and low switch ON resistance. These devices also have quiescent current, high output current, and wide input voltage operation. Switch ON resistance is on 31mΩ at VIN = 5.0V, - 0.15A load conditions. Toshiba TCK1024G Load Switch ICs also feature a thermal shutdown function and output auto-discharge function. Housed in an ultra-small WCSP6E package measuring only 0.8mm x 1.2mm, these load switch ICs are ideal for space-critical portable applications.
