L6474 Fully integrated microstepping motor driver Datasheet - production data Applications Bipolar stepper motor Description The L6474 device, realized in analog mixed POWERSO36 HTSSOP28 signal technology, integrates a dual low R DS(on) DMOS full bridge with all power switches equipped with an accurate on-chip current sensing circuitry suitable for non-dissipative Features current control and overcurrent protections. Thanks to a new current control, a 1/16 Operating voltage: 8 - 45 V microstepping is achieved through an adaptive 7.0 A output peak current (3.0 A ) r.m.s. decay mode which outperforms traditional Low R power MOSFETs implementations. DS(on) Programmable power MOS slew rate All data registers, including those used to set analogue values (i.e.: current control value, Up to 1/16 microstepping current protection trip point, deadtime, etc.) are Current control with adaptive decay sent through a standard 5 Mbit/s SPI. Non-dissipative current sensing A very rich set of protections (thermal, low bus SPI interface voltage, overcurrent) makes the L6474 device Low quiescent and standby currents bullet proof as required by the most demanding motor control applications. Programmable non-dissipative overcurrent protection on all power MOS Two-level overtemperature protection Table 1.
