L9942XP1TR - Brand New STMicroelectronics Motor Drivers and Controllers
-
Description
The L9942 is an integrated stepper motor driver for bipolar stepper motors with microstepping and programmable current profile look-up-table to allow a flexible adaptation of the stepper motor characteristics and intended operating conditions.
It is possible to use different current profiles depending on target criteria: audible noise, vibrations, rotation speed or torque.Features
■ Two full bridges for max. 1.3 A load (RDSON= 500 m)
■ Programmable current waveform with look-up table: 9 entries with 5 bit resolution
■ Current regulation by integrated PWM controller and internal current sensing
■ Programmable stepping mode: full, half, mini and microstepping
■ Programmable slew rate for EMC and power dissipation optimization
■ 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 short circuit protected with openload, overload current, temperature warning and thermal shutdown
■ The PWM signal of the internal PWM controller is available as digital output.
■ All parameters are guaranteed for 3 V < Vcc < 5.3 Vand for 7 V < Vs < 20 V
