SLA7060M series is a two-phase unipolar stepper motor translator/driver, integrated with internal fixed off time and pulse-width modulation (PWM) control of the output current in a power multi-chip module (PMCM™). With low-power CMOS logic and high-current, high-voltage power FET outputs, it has no phase-sequence tables, high-frequency control lines, or complex interfaces to program.
The SLA7060M‑62M series are unipolar stepper‑motor translator/drivers that combine low‑power CMOS logic with high‑current, high‑voltage power‑FET outputs. They provide built‑in microstepping, PWM current control, sleep mode, and internal clamp diodes, requiring only a few control signals such as CLOCK, RESET, M1, M2, and direction inputs.
The devices are supplied in a 21‑pin single‑in‑line tab (LF2102) package, operate from 10‑44 V driver supply, and support output currents up to 3 A (depending on part). They offer half‑, quarter‑, eighth‑ and sixteenth‑step modes selectable via M1/M2 inputs, and include features such as internal sequencing, synchronous operation, and monitoring outputs.
| Logic Supply Voltage Range | 3.0 V to 5.5 V |
|---|---|
| Typical Output On‑Resistance (Rds(on)) | 700 mΩ (1 A), 250 mΩ (2 A), 180 mΩ (3 A) |
| Body Diode Forward Voltage (typ.) | 0.85 V (1 A), 0.95 V (2 A), 0.95 V (3 A) |
| Maximum Junction Temperature | +150 °C |
| Package Type | 21‑pin single‑in‑line tab (LF2102) |
The device supports half‑step, quarter‑step, eighth‑step and sixteenth‑step modes selectable via the M1 and M2 inputs.
Applying a voltage greater than 2 V to the REF pin disables the outputs and puts the motor in a free (coast) state, entering sleep mode.
The recommended mounting hardware torque is 0.490 – 0.822 Nm.
