Load Switch ICs feature ultra-low ON resistance.

Toshiba Introduces New Ultra-Low ON Resistance Load Switch ICs

Featuring Reverse Current Blocking and Thermal Shutdown Function

IRVINE, Calif. -- 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:
R(ON) = 8.3 mΩ (typ.) at V(IN) = 5.0 V, -1.5 A
R(ON) = 8.4 mΩ  (typ.) at V(IN) = 3.3 V, -1.5 A
R(ON) = 8.4 mΩ  (typ.) at V(IN) = 1.8 V, -1.5 A
R(ON) = 8.5 mΩ  (typ.) at V(IN) = 1.1 V, -1.5 A
--  Wide input voltage operation: V(IN) = 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.))
