12 / 42 page  General description UM1692 12/42 DocID025487 Rev 2 4.2 L6472 stepper motor driver The L6472 is an advanced fully integrated solution suitable for driving two-phase bipolar stepper motors with microstepping. It integrates a dual low RDS(on) DMOS full bridge. Features Operating voltage: 8 - 45 V 7.0 A out peak current (3.0 A r.m.s.) Low RDS(on) power MOSFETs Programmable speed profile Programmable power MOS slew rate Predictive current control with adaptive decay Non-dissipative current sensing Up to 1/16 microstepping Sensorless stall detection SPI interface Low quiescent and standby currents Programmable non-dissipative overcurrent Two levels of overtemperature protection Figure 7.
