Unipolar stepper-motor translator/pwm driver.
SLA7052M, UNIPOLAR STEPPER-MOTOR TRANSLATOR/PWM DRIVER
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.
When the voltage across the current-sense resi
or r t o ive M r D SLA7052M UNIPOLAR STEPPER-MOTOR TRANSLATOR/PWM DRIVER Combining low-power CMOS logic with high-current, high-voltage power FET outputs, the SLA7052M 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/asynchron
