Toshiba America Electronic Components (TAEC) has recently unveiled a new line-up of load switch ICs for mobile devices. The new line-up uses the company's newly developed micro CMOS process and features low voltage operation and low ON-resistance characteristics in ultra-small packages.

Toshiba's new line-up of 200mA output LDO regulators control inrush current, making them suitable for a wide range of applications including mobile phones, portable audio players, notebook PCs, DSC/DVC, and other small mobile devices.

The TCK101G and TCK102G are low consumption current load switch ICs with a slew rate control driver for power management. Featuring low voltage operation at 1.1V and a low ON-resistance characteristics of 55m ohms (typ.) (VIN = 3.3V, IOUT = 500mA) in a 0.4mm pitch ultra-small WCSP6 (0.8mm x 1.2mm, t: 0.64mm (max.)) package, these ICs come standard with an inrush current limiter and over temperature protection circuit. An output auto-discharge function is also available.

The company's latest devices are load switch ICs for power management and current limit function featuring wide input voltage operation from 1.1 to 5.5V. They feature low switch ON- resistance at 65m ohms typical at 3.3V, 700mA load condition and a slew rate control driver, with thermal shutdown and an output auto-discharge function. Output current type is available, simplifying device selection and design. Available in a 0.4mm pitch ultra-small package WCSP6 0.8x1.2x0.64mm (max), these devices are ideal for portable applications that require high-density board assembly C including mobile phones.

Toshiba is also offering the TCK106G, TCK107G and TCK108G which are available in the ultra-small WCSP4 package with a 0.64mm 2 foot print.

Features include:

  • Wide input voltage operation: VIN = 1.1 to 5.5V
  • Low ON-resistance
  • Low quiescent current:
  • Low standby current: IQ(OFF) = 0.1?A (typ) in stand-by mode
  • Inrush current reducing circuit
  • Thermal shutdown function
  • Auto-discharge available
  • Pull down connection between CONTROL and GND
  • Ultra-small package: WCSP6B (0.8x1.2x0.64mm(max)), WCSP4 (0.79x0.79x0.5mm(typ))
