Overview
The A6861KLPTR-T is an automotive-grade three-phase isolator gate driver manufactured by Allegro MicroSystems. It operates within a supply voltage range of 4.5 V to 50 V and supports junction temperatures from -40°C to +150°C. The device features three outputs with a drive current capability of 10 mA and consumes 10 mA of operating supply current. Packaged in a TSSOP-16 surface-mount format, it is designed for brushless DC motor control applications requiring phase isolation.
Feature Summary
- Provides galvanic isolation between control logic and power stages for three-phase BLDC motors
- Integrated high-side and low-side gate driving capabilities for direct MOSFET control
- Designed for harsh automotive environments with extended temperature tolerance
Applications
- Automotive brushless DC (BLDC) motor control systems
- Three-phase motor drives requiring electrical isolation
- Electric vehicle auxiliary motor applications
Procurement Notes
Verify the complete part number including suffixes against official Allegro MicroSystems documentation to ensure correct package and tape/reel specifications. Confirm RoHS compliance status and humidity sensitivity level requirements prior to ordering. Ensure design compatibility with the specified 4.5 V to 50 V supply range and TSSOP-16 thermal characteristics.
Selection Notes
Select this component when designing automotive BLDC motor drivers that require integrated isolation between the controller and power switches. Compare against similar isolator gate drivers based on output current capacity, operating temperature range, and package footprint. Ensure the 10 mA drive current meets the gate charge requirements of the target MOSFETs.
Part Context
This device belongs to the A6861 series of automotive isolator gate drivers. It is distinct from non-isolated gate drivers and serves as a bridge between low-voltage control signals and high-voltage power stages. The KLPTR-T suffix indicates the specific TSSOP-16 package and reel packaging configuration.
Replacement Considerations
Consult official Allegro MicroSystems substitution guides for verified alternatives. Cross-reference pinouts and electrical parameters carefully when considering competitors.
