A3952SW Datasheet | Allegro MicroSystems

Data Sheet 29319.1C FULL-BRIDGE PWM MOTOR DRIVER A3952SB Designed for bidirectional pulse-width modulated current control of inductive loads, the A3952S- is capable of continuous output currents to ±2 A and operating voltages to 50 V. Internal fixed off-time PWM BRAKE 1 REF 2 LOAD SUPPLY current-control circuitry can be used to regulate the maximum load current to a desired value. The peak load current limit is set by the 15 OUTB user’s selection of an input reference voltage and external sensing resistor. The fixed OFF-time pulse duration is set by a user-selected RC 3 14 MODE external RC timing network. Internal circuit protection includes thermal GROUND 4 GROUND 5 T LOGIC SUPPLY C PHASE 7 U ENABLE 8 LOGIC VBB 13 GROUND 12 GROUND 11 SENSE 10 OUTA LOAD 9 SUPPLY OD Dwg. PP-056 Note that the A3952SB (DIP) and the A3952SLB R ly (SOIC) are electrically identical and share a mon terminal number assignment. D P On ign...
