Overview
The SG1731J-883B is a high-reliability DC motor pulse width modulator manufactured by Microchip Technology. It operates within a supply voltage range of ±3.5 V to ±15 V and supports switching frequencies between 5 kHz and 350 kHz. The device functions as a PWM controller designed for motion control applications. It is housed in a 16-lead Ceramic Dual In-Line Package (CDIP) with a 0.300-inch (7.62 mm) body width. The component is qualified under MIL-STD-883 standards, ensuring suitability for demanding environments.
Feature Summary
- High-reliability construction suitable for military and aerospace specifications
- Integrated pulse width modulation control for DC motor applications
- Wide operating temperature range supporting extreme environmental conditions
Applications
- DC motor speed control systems
- Motion control electronics
- Military-grade power management modules
Procurement Notes
Verify the specific suffix J-883B against official Microchip documentation to confirm MIL-STD-883 Class B qualification status. Ensure the CDIP-16 package matches system requirements. Confirm RoHS exemption status as military parts often lack standard compliance certifications. Validate authenticity through authorized distribution channels due to the specialized nature of this component.
Selection Notes
Select this component when designing systems requiring certified high-reliability PWM control for DC motors. The wide frequency range allows flexibility in filter design. Consider the ceramic package for superior thermal and mechanical stability compared to plastic alternatives. Verify that the ±3.5 V to ±15 V input range aligns with the target power supply architecture.
Part Context
This part belongs to the SG1731 family of PWM controllers, specifically tailored for high-reliability applications. The 'J' indicates a military grade variant, while '883B' denotes compliance with MIL-STD-883 test methods. It serves as a specialized interface between logic controls and power stages in critical motion control systems.
Replacement Considerations
Direct substitutes include other MIL-qualified PWM controllers from Microchip or legacy equivalents like the SG1731L variants if package compatibility allows. Cross-reference pinouts and electrical characteristics carefully before substitution.
