7-Channel DMOS Transistor Array for Industrial and Agricultural Automation
![7-Channel DMOS Transistor Array](/sites/default/files/components/7-Channel-DMOS-Transistor-Array.jpg)
Diodes Incorporated has introduced the new transistor arrayULN62003Athat consists of seven 500mA-rated open-drain transistors, where all their sources are connected to a common ground pin. Capable of driving a wide variety of loads, such as solenoids, relays, DC motors, and LED displays, this high-current transistor array is aimed at climate control and home appliance designs. Fabricated with DMOSFET output transistors, the ULN62003A has an output voltage drop of just 0.2V which is far lower than the bipolar devices with which it is pin-compatible.
This device, with its support for input voltages down to -1V, has much greater flexibility and allows the GND pin to be used for detecting overcurrent situations. This capability further increases system robustness and broadens the applications that the ULN62003A can address. Clamping diodes are included on each of this transistor array’s outputs for protection and improved reliability when driving inductive loads.
