Overview
The LS7262C is a MOS integrated circuit designed by LSI/CSI to generate control signals for three-phase or four-phase brushless DC motors. It operates with a supply voltage range of 5V to 28V and features six half-bridge outputs capable of delivering 4.5mA per output. The component is available in multiple package configurations, including a 20-pin DIP (LS7262C), a 20-pin SOIC (LS7262C-S), and a 20-pin TSSOP (LS7262C-TS). It is RoHS3 compliant and supports external oscillator frequency adjustment via an external resistor.
Feature Summary
- Generates necessary drive signals for controlling three-phase or four-phase brushless DC motors
- Integrates NMOS and PMOS driver stages within a single MOS IC architecture
- Supports external oscillator configuration for flexible speed control applications
Applications
- Three-phase brushless DC motor control systems
- Four-phase brushless DC motor control systems
- Electronic speed controller designs requiring integrated driver logic
Procurement Notes
Verify the specific package suffix when ordering, as LS7262C denotes the DIP variant, while LS7262C-S indicates SOIC and LS7262C-TS indicates TSSOP. Confirm RoHS3 compliance requirements if applicable to your manufacturing standards. Ensure the input signal levels are compatible with the specified 5V to 28V supply range before integration into the final design.
Selection Notes
Select this component when designing controllers for BLDC motors requiring integrated signal generation and driving capabilities. Consider the package type based on PCB layout constraints, choosing between DIP, SOIC, or TSSOP formats. Verify that the required output current of 4.5mA meets the gate drive requirements of the connected motor phases.
Part Context
The LS7262C belongs to the LS726 series of LSI circuits from LSI/CSI, which also includes variants like the LS7260C and LS7261. These components are specifically engineered for motor control applications, providing a consolidated solution for generating commutation signals and driving power stages in brushless DC motor systems.
Replacement Considerations
Direct substitutes include other members of the LS726 family such as the LS7260C or LS7261, provided they support the same phase configuration and electrical characteristics. Package-specific equivalents exist, such as the LS7262C-S for SOIC or LS7262C-TS for TSSOP, offering form-factor alternatives without changing functionality.
