Overview
The LV8747TA-NH is a fully integrated control and power stage motor driver optimized for bipolar stepper motor operation. It features two-channel PWM constant-current control, enabling W1-2 phase excitation modes. The device utilizes a push-pull output structure to support high-speed running capabilities. Integrated within the chip are two switching regulator controllers, which assist in external power management. The component operates with a supply voltage range of 10 V to 35 V and includes built-in timer latched short-circuit protection for enhanced reliability.
Feature Summary
- Integrated two-channel PWM constant-current control for precise stepping motor regulation
- Push-pull output stage architecture designed to facilitate high-speed motor operation
- Built-in timer latched short-circuit protection mechanism for system safety
Applications
- Bipolar stepper motor drive systems
- Industrial automation motion control
- High-speed positioning applications
Procurement Notes
Verify the specific suffix NH against official onsemi documentation to confirm pinout and thermal characteristics. Ensure the application environment remains within the specified -20 °C to 85 °C operating temperature range. Confirm RoHS compliance requirements align with project specifications before finalizing procurement orders.
Selection Notes
Select this component when designing bipolar stepper motor drivers requiring integrated PWM constant-current control. The TQFP-64 package suits applications needing multiple outputs and robust thermal performance. Consider the integrated switching regulator controllers if external power management simplification is required for the target design.
Part Context
This part belongs to onsemi's lineup of motor driver solutions. It is distinct from evaluation boards like the LV8746VGEVB or other linear regulators such as the NCV8737 series. The LV8747TA-NH specifically addresses bipolar stepper motor needs with integrated power stages and control logic.
Replacement Considerations
Consult official cross-reference data for verified substitutes. Generic equivalents may lack the specific timer latched protection or W1-2 phase excitation capabilities documented for this model.
