TB67S581FNG BiCD constant current two-phase bipolar stepper motor driver IC 1. Description: The TB67S581FNG is a two-phase bipolar stepper motor driver IC that uses a PWM chopper. Made using BiCD technology, TB67S581FNG has a rated value of 50 V/2.5 A. The built-in voltage regulator for IC operation allows the motor to be driven by a single VM power supply.
TB67S581FNG features: BiCD process integrated with a single chip IC, capable of controlling bipolar stepper motors, attenuation mode selection function (mixed attenuation/slow attenuation/fast attenuation), power-saving function (sleep mode), clock input control, 3.3 V regulator output, allowing full step, half step, quarter step, 1/8, 1/16, 1/32 step operation, BiCD structure: DMOSFET is used to output power transistors. High breakdown voltage and high current: 50 V/2.5 A (absolute maximum rated value). Built in thermal shutdown detection (TSD), overcurrent detection (ISD), and undervoltage lock detection (UVLO). Error detection flag output function (nFAULT). Reduce the number of external components by reducing charge pumps. Package: P-HTSSOP28-0510-0.65-001
