Description and Introduction

Three-Phase Brushless Motor Driver for Portable VCR Capstan Motors The LB1991 is a bipolar stepper motor driver IC designed for controlling stepper motors in various applications. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer Specifications:**  
- **Manufacturer:** ON Semiconductor (formerly part of Sanyo Semiconductor)  
- **Type:** Bipolar Stepper Motor Driver IC  
- **Operating Voltage Range:** 4.5V to 5.5V (logic supply), 10V to 46V (motor supply)  
- **Output Current:** Up to 1.5A per phase (with proper heat dissipation)  
- **Package Type:** SIP (Single In-line Package) or ZIP (Zigzag In-line Package)  
- **Number of Pins:** 16  

### **Descriptions:**  
- The LB1991 is a unipolar/bipolar stepper motor driver IC capable of driving two-phase stepper motors.  
- It includes built-in protection features such as thermal shutdown and overcurrent protection.  
- The IC supports full-step, half-step, and microstepping modes for precise motor control.  
- It is commonly used in printers, scanners, robotics, and other automation systems requiring stepper motor control.  

### **Features:**  
- **Bipolar Output:** Supports both unipolar and bipolar stepper motor configurations.  
- **Built-in Protection:** Thermal shutdown and overcurrent protection for safe operation.  
- **Multiple Excitation Modes:** Full-step, half-step, and microstepping control.  
- **Low Power Consumption:** Efficient power management with standby mode support.  
- **High Voltage Tolerance:** Motor supply voltage up to 46V.  
- **Easy Control Interface:** Compatible with microcontroller and logic-level inputs.  

This information is strictly based on the available knowledge base for the LB1991 stepper motor driver IC.
