SLA7083MPR
Description
This document describes the function and features of the SLA7080MPR series, which are unipolar 2-phase stepping motor driver ICs. Four levels of output current are available from the incorporated MOSFETs, corresponding to the rated output current ratings.
Key Features
- Power supply voltage, VBB, 46 V maximum; 10 to 44 V normal operating range
- Logic supply voltage, VDD, 3 to 5.5 V
- Four output currents, IO(max), options: 1, 1.5, 2, and 3 A
- Stepping control for phase input (full or half step)
- Built-in sense resistor detects motor current
- pact ZIP 23-pin molded package (SLA package)
- Self-excitation PWM control with fixed off-time
- Built-in synchronous rectifying circuit reduces losses at PWM-off
- Synchronous PWM function prevents noise generation in motor Hold mode
- Sleep function reduces power consumption of drivers in Standby mode
