Description and Introduction

100mA CHARGE PUMP DC-TO-DC VOLTAGE CONVERTER The TC660COA is a stepper motor driver IC manufactured by Microchip Technology. Below are its specifications, descriptions, and features based on the available knowledge base:

### **Specifications:**  
- **Supply Voltage (VDD):** 5V to 12V  
- **Output Current (per phase):** Up to 750mA  
- **Step Modes:** Full-step, half-step, and microstepping (via external clock)  
- **Logic Input Voltage:** 3.3V or 5V compatible  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 16-pin SOIC (Small Outline Integrated Circuit)  

### **Description:**  
The TC660COA is a PWM (Pulse Width Modulation) microstepping motor driver designed for bipolar stepper motors. It integrates control logic, power MOSFETs, and protection features, reducing the need for external components. It is commonly used in applications requiring precise motion control, such as robotics, CNC machines, and automation systems.

### **Features:**  
- **Microstepping Capability:** Supports smooth motor operation with reduced vibration.  
- **Built-in PWM Current Control:** Maintains consistent torque across speeds.  
- **Thermal Shutdown Protection:** Prevents overheating damage.  
- **Undervoltage Lockout (UVLO):** Ensures safe operation under low voltage conditions.  
- **Direction and Step Inputs:** Simple interfacing with microcontrollers or logic circuits.  
- **Low External Component Count:** Reduces system complexity and cost.  

For exact performance parameters, always refer to the official **TC660COA datasheet** from Microchip Technology.
