SN74BCT8373ADWR

The SN74BCT8373ADWR is a high-speed auto-sense dual power driver. This low-power device integrates two high-current drivers that operate from either a single-ended input or a complementary balanced drive. The SN74BCT8373ADWR is part of the linear logic series of components offered by Texas Instruments. It is classified under specialty logic and has a wide variety of design applications.

The SN74BCT8373ADWR is designed to drive power-sensitive loads such as transistors or small motor controllers. It features two integrated H-Bridges, 25 mA drive, individual enable pins, as well as over-current and short-circuit protection. The device is available in both 16-pin dual-in-line package (PDIP) and 16-pin small-outline IC (SOIC) packages.

The SN74BCT8373ADWR is built using a high-speed CMOS process and incorporates two high-current drivers. The drivers are constructed from a depletion-mode N-channel FET transistor and a P-channel FET transistor and are capable of operating from either a single-ended input or a complementary and balanced drive. The device also includes a Schmitt trigger input stage, which filters out any noise on the input.

The SN74BCT8373ADWR operates in four different modes, depending on the logic state of the enable pins. When both enable pins are logic low, the drivers are disabled and the output is effectively tri-stated. When the left enable pin is high, while the right enable pin is low, the device operates in single-ended drive mode to deliver up to 25 mA of drive current. When the left enable pin is low, while the right enable pin is high, the device operates in complementary drive mode and can deliver up to 50 mA of drive current.

The SN74BCT8373ADWR also provides over-current and short-circuit protection. When over-current is detected, the device turns off both outputs, providing further protection to the load. Similarly, when a short-circuit is detected, the device momentarily disables the outputs, before turning them back on.

The SN74BCT8373ADWR is ideal for driving power-sensitive loads such as motor controllers or transistors. It features low standby current (typ 450 μA) and ESD ruggedness (to 16 kV). This makes it well suited for many applications, including motor control, power switch control, and other high-power operations.

In conclusion, the SN74BCT8373ADWR is an ideal device for powering all types of power-sensitive loads. Its integrated drivers provide exceptional drive current and protection, making it an excellent choice for a wide variety of applications, from motor control to power switch control.
