Description and Introduction

Stepping motor driver IC The TB6615PG is a motor driver IC manufactured by Toshiba. Here are its specifications, descriptions, and features based on the available knowledge:

### **Specifications:**
- **Manufacturer:** Toshiba  
- **Type:** H-Bridge Motor Driver IC  
- **Operating Voltage (VM):** 2.5V to 13.5V  
- **Output Current (Continuous):** 1.2A (per channel)  
- **Output Current (Peak):** 3.2A (per channel)  
- **Number of Channels:** 2 (Dual H-Bridge)  
- **Control Interface:** PWM input for speed control, logic-level inputs for direction control  
- **Low On-Resistance:** 0.3Ω (Upper + Lower, HS + LS)  
- **Thermal Shutdown Protection:** Yes  
- **Undervoltage Lockout (UVLO):** Yes  
- **Package:** P-VQFN24 (4mm x 4mm)  

### **Descriptions:**
- The TB6615PG is a dual H-bridge motor driver capable of driving two DC motors or one stepper motor.  
- It supports bidirectional control with PWM speed regulation.  
- Designed for low-voltage applications, it is suitable for battery-powered devices.  
- Includes built-in protection features like thermal shutdown and UVLO for safe operation.  

### **Features:**
- **Low Power Consumption:** Optimized for energy-efficient applications.  
- **Compact Package:** Small form factor (VQFN24) for space-constrained designs.  
- **High Efficiency:** Low on-resistance minimizes power loss.  
- **Standby Mode:** Reduces power consumption when not in use.  
- **Wide Operating Voltage Range:** Supports various power sources.

Application Scenarios & Design Considerations

Stepping motor driver IC

Alternative Part Number

  • L293D --: Classic dual H-bridge motor driver in DIP package, widely available and functionally similar to the TB6615PG for driving two DC motors.
  • DRV8833 --: Dual H-bridge motor driver with comparable voltage and current ratings, low on-resistance, and a common modern replacement for older Toshiba drivers.
  • L298N --: Dual full-bridge motor driver with higher current capability, commonly used as a drop-in style alternative when board space and pinout allow.
