STK672-631AN-E

Overview

The STK672-631AN-E is a hybrid integrated circuit designed for brushless DC (BLDC) motor applications. It functions as a fully integrated driver combining control logic and power stages. The component utilizes a parallel interface for command input. It operates within a supply voltage range of 4.75 V to 5.25 V. The device supports a typical switching frequency of 45 kHz. It features a single in-line package (SIP) with 19 pins. The maximum collector-emitter voltage rating is 42 V, and the peak collector current reaches 2.2 A. Operating temperatures span from 0°C to +105°C.

Feature Summary

• Fully integrated control and power stage for BLDC motors
• Built-in PWM current control capability
• Parallel interface for digital signal processing

Applications

• Brushless DC motor drives
• Office photocopiers
• Printers

Procurement Notes

Verify the manufacturer designation carefully, as this part number is frequently associated with ON Semiconductor or onsemi product lines rather than Flip Electronics. Flip Electronics acts primarily as a distributor. Confirm the datasheet source matches the specific electrical characteristics required for your design. Ensure the SIP-19 package dimensions align with your PCB footprint constraints before finalizing procurement.

Selection Notes

Select this component when a fully integrated solution for BLDC motor control is required without external logic gates. The 42 V voltage rating suits low-voltage industrial applications. The 2.2 A current capacity defines the maximum load limits. Consider the 19-pin SIP package for through-hole mounting requirements. Verify compatibility with parallel interface protocols used by the host microcontroller.

Part Context

This hybrid IC belongs to the STK672 series of stepper and BLDC motor drivers. It shares architectural similarities with models like the STK672-630AN-E and STK672-632AN-E. These components typically integrate gate drivers, protection circuits, and control logic into a single module. The series is designed to simplify motor drive circuit design by reducing component count.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference checks indicate potential functional equivalents within the STK672 family, such as the STK672-630AN-E, but specific pin-to-pin compatibility and parameter matching require verification against official manufacturer substitution lists.
