Toshiba Introduces New Ultra-Low ON Resistance Load Switch ICs

Featuring Reverse Current Blocking and Thermal Shutdown Function

IRVINE, Calif., July 15, 2014 — (PRNewswire) — Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced two new ultra-low ON resistance load switch ICs, the TCK111G and TCK112G, for power management in portable/mobile devices, such as smart phones, that require high-density board assembly.

The new load switch ICs offer reverse current blocking and a thermal shutdown function.  In addition, they feature ultra-low switch ON resistance, low quiescent current and a wide input voltage operation from 1.1 V to 5.5 V. Switch ON resistance is only 8.3 mΩ at 5.0 V and -1.5 A for load conditions. The TCK111G and TCK112G also feature an inrush current suppressing slew rate control driver and output auto-discharge function (offered as an option on the TCK112G).

Available in a 0.5 mm pitch ultra-small package WCSP6C (1.0 mm x 1.5 mm, t: 0.5 mm (typ.)) the new devices from Toshiba are well-suited to smart phones but are also targeted to tablet PCs, portable audio players, digital cameras, camcorders, games and other small mobile devices.

Features:

  • Low ON resistance:
    RON = 8.3 mΩ (typ.) at VIN = 5.0 V, -1.5 A
    RON = 8.4 mΩ (typ.) at VIN = 3.3 V, -1.5 A
    RON = 8.4 mΩ (typ.) at VIN = 1.8 V, -1.5 A
    RON = 8.5 mΩ (typ.) at VIN = 1.1 V, -1.5 A
  • Wide input voltage operation: VIN = 1.1 to 5.5 V
  • Reverse current blocking
  • Inrush current reducing circuit
  • Thermal shutdown function
  • Built in auto-discharge (TCK112G)
  • Pull down connection between CONTROL and GND
  • Ultra-small package: WCSP6C (1.0 mm x 1.5 mm, t: 0.5 mm (typ.))
