Overview
The L9925 is a dual full bridge driver integrated circuit designed for stepper motor applications. It is realized in BCD (Bipolar, CMOS & DOS) technology, integrating logic circuits and precise linear blocks. The device operates with a supply voltage range of 9V to 16V. It features an operating temperature range from -40°C to 150°C (TJ). The output configuration consists of four half bridges. The component is housed in a 28-SO package.
Feature Summary
- Dual full bridge architecture optimized for bipolar stepper motor control
- Integrated BCD technology combining logic circuits and linear blocks
- Wide thermal operating capability suitable for extreme environments
Applications
- Stepper motor control systems
- Bipolar motor drive applications
- Safety critical motor control under extreme environmental conditions
Procurement Notes
Verify the specific package variant and revision level against the manufacturer's current documentation before procurement. Confirm that the intended application aligns with the specified voltage and temperature ranges. Check for any obsolete status or lifecycle changes as availability may vary. Ensure compatibility with the host system's logic levels and power requirements.
Selection Notes
Select this component when a dual full bridge solution for bipolar stepper motors is required. Consider the BCD technology integration for simplified design. Evaluate the 28-SO package constraints against PCB layout requirements. Verify that the 9V-16V supply range matches the system power architecture.
Part Context
This part belongs to STMicroelectronics' interface IC portfolio, specifically within the motor driver category. It serves as a dedicated solution for controlling bipolar motors, distinct from general-purpose H-bridge drivers. The device integrates necessary control logic, reducing external component count compared to discrete solutions.
Replacement Considerations
