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.
Features
- Two full bridges for max. 1.3 A load (RDSON = 500 mī).
- 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 AutoDecay Mode.
- Full-scale current programmable with 3 bit resolution.
- Pro.
