Overview
The DRV777DR is a 7-bit integrated motor and relay driver manufactured by Texas Instruments. It features an NMOS technology with a parallel interface, designed for unipolar stepper motors and brushed DC applications. The device operates within a supply voltage range of 5V to 20V and supports a load voltage of the same range. It provides a continuous output current of 1A per channel across seven low-side outputs. The component is housed in a 16-SOIC package and functions reliably within an operating temperature range of -40°C to 125°C.
Feature Summary
- Integrates control logic and power stage for simplified system design
- Supports wide input voltage ranges for flexible power configurations
- Compatible with standard parallel digital interfaces
Applications
- Unipolar stepper motor control systems
- Brushed DC motor driving circuits
- General-purpose relay switching applications
Procurement Notes
Verify the specific suffix 'DR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 16-SOIC footprint matches the target PCB layout dimensions. Ensure the thermal requirements for the SOIC package are addressed in the design phase to maintain operation within the specified junction temperature limits during high-load scenarios.
Selection Notes
Choose this component when a single IC solution is needed to drive multiple low-side loads without external discrete transistors. It is suitable for designs requiring moderate current handling up to 1A per channel. Consider the 16-pin package constraint and the need for parallel control signals when evaluating alternative drivers with different pin counts or serial interfaces.
Part Context
This part belongs to the DRV777 family of integrated drivers from Texas Instruments. It consolidates the functionality of separate logic and power components into a single monolithic circuit. The series is engineered for cost-effective solutions in consumer electronics and industrial automation where space efficiency and reduced bill-of-materials complexity are prioritized over high-power delivery.
Replacement Considerations
Direct substitutes include other parts within the DRV777 family such as the DRV777, provided the packaging and suffix specifications align with the system requirements. Verify pin compatibility and electrical ratings before swapping.
