STA7132MPR Datasheet, PDF (1/2 Pages) Sanken electric – 2-Phase to 2W 1-2 Phase Excitation Support, Built-in Sequencer

1-2-1 2-Phase Stepper Motor Unipolar Driver ICs
STA7130MPR/7131MPR/7132MPR 2-Phase to 2W 1-2 Phase Excitation Support, Built-in Sequencer
■Features
• Lineup of built-in current sense resistor and
built-in protection circuit-type
• Power supply voltages, VBB: 46 V (max), 10 to
44 V normal operating range
• Maximum output currents: 1 A, 1.5 A, and 2 A
• Supporting the clock-input-method micro-step
drive (built-in sequencer)
• Self-excitation PWM current control with fixed
off time
• Synchronous PWM chopping function
prevents motor noise in Hold mode
• Sleep mode for reducing the IC input current
in stand-by state
• ZIP type 18-pin molded package (STA
package)

*1: Output current value may be limited for the STA7130MPR (1.0 A), 7131MPR (1.5 A), and 7132MPR (2.0 A),
depending on the duty ratio, ambient temperature, and heating conditions.
Do not exceed junction temperature of Tj under any circumstances.
