L9942 Datasheet - ST Microelectronics

L9942 Integrated stepper motor driver

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 dependi.

L9942 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
