Pinout
The HR871190A is a 32-pin IC primarily used as a motor driver for stepper motors. Key functions include:
- Phase current control (adjustable via external resistors).
- Microstepping support (up to 1/16 step).
- Built-in PWM chopper for current regulation.
- Protection features: Overcurrent, thermal shutdown, and undervoltage lockout.
Pins are allocated for:
- Power supply (VM, VCC, GND).
- Logic inputs (STEP, DIR, ENABLE).
- Motor outputs (A1, A2, B1, B2).
- Configuration (current sense, decay mode).
Exact pinout varies by datasheet—refer to the manufacturer's documentation for specifics.
