Overview
The TCA3727NKLA1 is a bipolar monolithic integrated circuit designed for driving bipolar stepper motors, DC motors, and other inductive loads operating on constant current. Manufactured by Infineon Technologies, this component integrates the driver, control logic, and power stage into a single unit. It operates within a supply voltage range of 4.5V to 6.5V and supports load voltages from 5V to 50V. The device delivers an output current of 1A and features four half-bridge outputs. It is housed in a 20-DIP (P-DIP-20-6) package with through-hole mounting capabilities.
Feature Summary
- Integrates full driver, control logic, and power stage for simplified design
- Supports full, half, quarter, and mini-step resolution modes
- Features fast free-wheeling diodes and offset-phase turn-on to prevent crossover current
Applications
- Bipolar stepper motor control systems
- DC motor drive applications
- Inductive load switching circuits
Procurement Notes
Verify component authenticity as the TCA3727NKLA1 is listed as obsolete or discontinued by the manufacturer. Confirm availability of alternative packages such as the SOIC variant if surface mount is required. Ensure compliance with RoHS regulations, as this specific part number may not meet current environmental standards. Validate lead times and substitute options due to end-of-life status.
Selection Notes
Select this component for applications requiring a fully integrated bipolar stepper motor solution without external discrete drivers. It is suitable for designs needing multiple step resolutions including quarter and mini-stepping. Consider the DIP package constraint for PCB layout. Evaluate thermal performance given the 1A output capability and plastic encapsulation. Verify that the 4.5V to 6.5V logic supply range matches the system's control voltage.
Part Context
The TCA3727 series represents a family of bipolar stepper motor drivers produced by Infineon Technologies, formerly Siemens. This specific part number denotes the DIP package variant. The series is characterized by its ability to handle constant current loads and integrate chopper current control. It serves as a legacy solution for motion control applications where high integration and low component count are prioritized over modern surface-mount form factors.
Replacement Considerations
Public confirmed substitute part numbers include TCA3727G for surface mount requirements. Other variants like TCA3727IN may be considered depending on package preference. Verify pin compatibility and electrical specifications before substitution.
