Texas Instruments (TI) has introduced a 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%, 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.
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 units can be controlled with just three GPIO pins, providing a flexible, efficient solution.
