SLA7060M/61M/62M/65M/66M/67M
October 2005
■General Description
■Package
Combining low-power CMOS logic with high-current, high-voltage
power FET outputs, the Series SLA706xM translator/drivers provide
complete control and drive for a two-phase unipolar stepper motor
with internal fixed off time and pulse-width modulation (PWM)
control of the output current in a power multi-chip module
(PMCM™).
There are no phase-sequence tables, high-frequency control lines,
orcomplex interfaces to program.The CMOS logic section provides
the sequencing logic, direction,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. For PWM current
control, the maximum output current is determined by the user's
selection of a reference voltage and sensing resistor. The NMOS
outputs are capable of sinking up to 1, 2, or 3 A (depending on device)
and withstanding 46 V in the off state.
Clamp diodes provide protection against inductive transients. Special
power-up sequencing is not required.
Half-, quarter-, eighth-, and sixteenth-step operation are externally
selectable for the SLA7060/61/62M. Full-, Half-, quarter-, and
eighth-step operation are externally selectable for the
SLA7065/66/67M.
Half-step excitation alternates between the one-phase and two-phase
modes (A-AB-B-AB-A-AB-BAB),providing an eight-step sequence.
