First 7-channel, NMOS low-side driver replaces Darlington transistor arrays in high-voltage systems

Drop-in compatible relay driver reduces power, cost and board space

DALLAS, June 25, 2014 /PRNewswire/ -- Texas Instruments (TI) (NASDAQ: TXN) today introduced the industry´s first seven-channel, NMOS low-side driver, replacing standard Darlington transistor arrays with a power-efficient, drop-in compatible integrated circuit (IC). The TPL7407L replaces half of the transistor arrays required to drive high current loads, providing a new option for high voltage systems that previously required a number of transistor arrays or a motor driver. Reducing power by 40 percent, this new device efficiently drives the LED matrix, relay or stepper motor in high-voltage applications, such as white goods, building automation, lighting and HVAC. For more information or to order samples and an evaluation module, visit www.ti.com/tpl7407l-pr.

The TPL7407L complements TI´s broad portfolio of peripheral drivers, covering a wide voltage and current range, giving designers the ability to choose a device to suit their needs without extensive system redesign. When used with the SN74HC595 register, one or multiple TPL7404 can be controlled with just three GPIO pins, providing a flexible, efficient solution.

Key features and benefits of the TPL7407L:

Availability, packaging and pricing
The TPL7407L is available in 16-pin SOIC and TSSOP packages. Suggested retail pricing in 1,000-unit quantities starts at US$0.40. The TPL7407LEVM is also available for US$49.00, providing an easy way to evaluate device performance and operating characteristics.
