L9942XP - Brand New STMicroelectronics Motor Drivers and Controllers
-
Description
The L9942XP is an integrated stepper motor driver specifically designed for bipolar stepper motors. It features microstepping capabilities and a programmable current profile look-up-table, allowing for flexible adaptation to the motor's characteristics and operating conditions. Different current profiles can be used based on various criteria such as audible noise, vibrations, rotation speed, or torque.
Specifications and Features
- Two full bridges for a maximum load of 1.3 A (RDSON= 500 m) - Programmable current waveform with a look-up table: 9 entries with 5-bit resolution - Current regulation through an integrated PWM controller and internal current sensing - Programmable stepping modes: full, half, mini, and microstepping - Programmable slew rate for optimization of EMC and power dissipation - Programmable Fast-, Slow-, Mixed-, and Auto Decay Mode - Full-scale current programmable with 3-bit resolution - Programmable stall detection - Step clock input for reduced µController requirements - Very low current consumption in standby mode (IS < 3 µA, typ. Tj ≤ 85 °C) - All outputs are short circuit protected with openload, overload current, temperature warning, and thermal shutdown - The PWM signal of the internal PWM controller is available as a digital output - All parameters guaranteed for 3 V < Vcc < 5.3 V and for 7 V < Vs < 20 V
Application Scenarios
The L9942XP is suitable for a wide range of applications including:
- Motor drivers and controllers - Robotics - 3D printers - CNC machinesComparison
Advantages:- Versatile stepper motor driver with programmable current profiles and microstepping capabilities - Allows for flexible adaptation based on different target criteria - Low current consumption in standby mode
Disadvantages:- None identified
