Product Details
| One of the core features of A4983ET is its built-in PWM current control system, which automatically adjusts current to maintain stable operation, avoiding the complexity of external controllers. The chip adopts PWM control with fixed downtime, so that the motor can maintain good performance under different loads. Additionally, A4983ET offers safety mechanisms such as over-temperature protection (OTP), over-current protection (OCP), and under-voltage lockout (UVLO), ensuring that the chip is not damaged under extreme operating conditions. Its low RDS(on) MOSFET output stage reduces conduction losses and improves efficiency while reducing the need for heatsinks. To simplify design and improve ease of use, A4983ET uses simple STEP and DIR input signals to control the motor's direction of motion and step pattern. By varying the state of the MS1, MS2, and MS3 pins, users have the flexibility to select the desired microstep pattern to suit different application needs. The chip's TSSOP package design makes it suitable for space-constrained applications and has good thermal performance. A4983ET Stable operation over a wide temperature range of -40°C to 85°C, suitable for industrial-grade applications. |
