TB67S581FNG BiCD Constant-Current Two-phase Bipolar Stepping Motor Driver

The TB67S581FNG is a two-phase bipolar stepping motor driver IC using a PWM chopper. Fabricated with the BiCD process, the TB67S581FNG rating is 50 V / 2.5 A. The built-in regulator for IC operation allows the motor to be driven by a single VM power supply. P-HTSSOP28-0510-0.65-001 Weight: 0.105 g (Typ.) 2.
