TLE4205NKLA1

Overview

The TLE4205NKLA1 is a bipolar DC motor driver manufactured by Infineon Technologies, designed for automotive applications. It features two half-bridge outputs capable of delivering up to 1A per channel. The device operates within a supply and load voltage range of 6V to 32V. It utilizes a parallel interface and is housed in an 18-DIP (P-DIP-18-3) package with through-hole mounting. The component supports junction temperatures from -40°C to 150°C.

Feature Summary

• Full-integrated driver combining control and power stages for brushed DC motors
• Dual half-bridge output configuration for bidirectional motor control
• Automotive-grade qualification ensuring reliability in harsh environments

Applications

• Brushed DC motor control in automotive systems
• Actuator drive circuits requiring integrated protection
• Industrial motor control modules

Procurement Notes

Verify component status as the TLE4205NKLA1 is officially listed as obsolete or end-of-life. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB footprints for the 18-DIP package. Check RoHS compliance status, which may not meet current environmental standards. Validate technical specifications against original datasheets before integration into new designs.

Selection Notes

Select this component for applications requiring robust bipolar motor driving with high thermal tolerance. The 18-DIP package suits through-hole assembly processes. Consider the 1A output limit and 32V maximum voltage when sizing for specific loads. Evaluate alternative packages like the TLE4205G if surface-mount technology is required. Ensure the design accounts for the specified operating temperature range.

Part Context

The TLE4205 belongs to Infineon's dedicated motor driver family, offering integrated solutions for controlling brushed DC motors. This series provides complete driver functionality including logic inputs and power output stages. The NKLA1 suffix specifically denotes the through-hole DIP packaging variant, distinguishing it from surface-mount options within the same functional family.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The TLE4205G offers similar electrical characteristics but uses a PG-DSO-20-17 surface-mount package. Designers should verify pinout compatibility and thermal management requirements when considering package variations.
