SLA7051M - UNIPOLAR STEPPER-MOTOR TRANSLATOR/PWM DRIVER

Description

Internal PWM current control.

Each pair of outputs is controlled by a fixed off-time PWM current-control circuit that limits the load current to a desired value (ITRIP).

Initially, an output is enabled and current flows through the motor winding and RS.

Features

  • 2 A Output Rating Internal Sequencer for Full or Half-Step Operation PWM Constant-Current Motor Drive Cost-Effective, Multi-Chip Solution 100 V, Avalanche-Rated NMOS Low rDS(on) NMOS Outputs (300 mΩ typical) Advanced, Improved Body Diodes Half-Step and Full-Step Unipolar Drive Inputs Compatible with 3.3 V or 5 V Control Signals Sleep Mode Internal Clamp Diodes Always order by complete part number, e. g. , SLA7051MLF871 .

or r t o ive M r D SLA7051M UNIPOLAR STEPPER-MOTOR TRANSLATOR/PWM DRIVER Combining low-power CMOS logic with high-current, high-voltage power FET outputs, the SLA7051M translator/driver provides complete control and drive for a two-phase unipolar stepper motor with internal fixed off time, pulse-width modulation (PWM) control of the output current in a power multi-chip module (PMCM™). The CMOS logic section provides the sequencing logic, direction, full/half-step control, synchronous/asynchronous PWM operation, and a “sleep” function. The minimum CLOCK input is an ideal fit for applications where a complex µP is unavailable or overburdened. TTL or LSTTL may require the use of appropriate pull-up resistors to ensure a proper input-logic high.
