Overview
The SLA6870MZ LF2171 is a high-voltage three-phase motor driver manufactured by Sanken Electric. It integrates a 500V, 3A IGBT with built-in fast recovery diodes for the bridge circuit and pre-drive ICs featuring undervoltage lockout protection. Designed for brushless DC motor applications, it operates within a supply voltage range of 13.5V to 16.5V and supports load voltages up to 400V. The component utilizes a 24-SIP package with an exposed pad and through-hole mounting, suitable for home appliance environments.
Feature Summary
- Integrates 500V 3A IGBTs with built-in fast recovery diodes for three-phase bridge configurations
- Includes pre-drive ICs with undervoltage lockout protection functions
- Designed specifically for brushless DC motor control in home appliances
Applications
- Brushless DC (BLDC) motor drives
- Home appliance motor control systems
Procurement Notes
Verify the specific suffix LF2171 against official Sanken Electric documentation to confirm pinout and thermal characteristics. Ensure compatibility with existing PCB footprints for the 24-SIP package. Confirm that the operating temperature range meets system requirements. Check for any design-not-recommended status updates from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a fully integrated three-phase driver with high voltage tolerance is required. The internal IGBT and pre-drive logic simplify circuit design compared to discrete solutions. Consider the 24-SIP package constraints for thermal management and board space. Verify that the 3A output current rating aligns with the specific motor load requirements.
Part Context
This part belongs to Sanken's series of high-voltage three-phase motor drivers. It is engineered to replace older discrete designs by combining power switching and control logic into a single unit. The device targets cost-sensitive applications where reliability and compact size are critical, particularly in consumer electronics and white goods manufacturing sectors.
Replacement Considerations
Consult official Sanken Electric substitution guides for verified alternatives. Cross-reference pinouts and electrical ratings carefully. Generic replacements may lack the integrated protection features or specific voltage tolerances required for safe operation.
