A3966SLB-TR-T

The A3966SLB-TR-T is a kind of dual full-bridge PWM motor driver. It is designed to drive both windings of a twophase bipolar stepper motor. The device includes two H-bridges. For each bridge, a PHASE input controls load-current polarity by selecting the appropriate source and sink driver pair. It is available in 16-Lead SOIC package.

There are some features of A3966SLB-TR-T as follows: (1)±650 mA continuous output current; (2)30 V output voltage rating; (3)internal fixed-frequency PWM current control; (4)satlington sink drivers; (5)user-selectable blanking window; (6)internal ground-clamp & flyback diodes; (7)internal thermal-shutdown circuitry; (8)crossover-current protection and UVLO protection.

What comes next is about the maximum ratingsof A3966SLB-TR-T: (1)load supply voltage, VBB: 30 V; (2)output current, IOUT (peak): ±750 mA; (3)output current, IOUT (continuous): ±650 mA; (4)logic supply voltage, VCC: 7.0 V; (5)input voltage, Vin: -0.3 V to VCC + 0.3 V; (6)sense voltage, VS: 1.0 V; (7)package power dissipation (TA=25), PD: 1.87 W; (8)operating temperature Range, TA: -20 to +85; (9)junction temperature, TJ: +150; (10)storage temperature range, TS: -55 to +150.
