Overview
The SMA6865MH is a high-voltage three-phase motor driver designed for brushless DC (BLDC) and multiphase stepper motors. It supports a load voltage of up to 400V with a breakdown voltage of 500V. The device delivers an output current of 2.5A and operates on a supply voltage range of 13.5V to 16.5V. It features CMOS-compatible 5V inputs and includes built-in bootstrap diodes with 210Ω current-limiting resistors. The component functions within an operating temperature range of -20°C to 100°C.
Feature Summary
- Integrated overcurrent protection circuit with defined off-time periods
- Built-in bootstrap diodes equipped with 210-ohm limiting resistors
- CMOS-compatible input logic supporting 5V signal levels
Applications
- Fan motors for washing machines
- Pump motors for dryers
- Low- to medium-capacity BLDC motor drives
Procurement Notes
Verify the specific suffix 'MH' against official Sanken Electric documentation to confirm pinout and thermal characteristics. Ensure the application design accommodates the specified 13.5V to 16.5V supply range and 400V load voltage limits. Confirm that the 2.5A output current rating meets the peak requirements of the target motor without exceeding the device's thermal dissipation capabilities under maximum ambient conditions.
Selection Notes
Select this component when driving three-phase brushless DC or multiphase stepper motors requiring high-voltage tolerance up to 500V. It is suitable for applications needing direct CMOS 5V interface compatibility without additional level shifting. Consider its integrated protection features for cost-sensitive designs in home appliances where space constraints limit external protection components.
Part Context
This part belongs to Sanken Electric's series of high-voltage three-phase motor drivers rated for 1A to 3A output currents. It is engineered specifically for household appliance applications, offering a compact solution for controlling fan and pump motors. The series emphasizes integration by combining power MOSFETs with control logic and protection circuits in a single package.
Replacement Considerations
Consult official Sanken Electric substitution guides for verified equivalents. Cross-reference pinouts and electrical ratings carefully before replacing.
