Overview
The TC78H651AFNG,EL is a brushed DC motor driver IC manufactured by Toshiba Semiconductor and Storage. It features a half-bridge output configuration with four outputs, designed for surface-mount installation in a 16-TSSOP package. The device operates within a supply voltage range of 1.8V to 7.5V and delivers an output current of 2A. It functions across a wide temperature range from -40°C to +105°C, with a maximum power dissipation of 780 mW and a quiescent current of 600 uA.
Feature Summary
- Integrates DMOS technology for efficient power switching and control
- Includes built-in protection mechanisms against overcurrent and thermal issues
- Supports PWM input signals for precise motor speed regulation
Applications
- Brushed DC motor control in consumer electronics
- Motion control systems requiring compact driver solutions
- Industrial automation equipment utilizing small to medium power motors
Procurement Notes
Verify the specific suffix EL during procurement to ensure compatibility with reel packaging requirements. Confirm that the 16-TSSOP package dimensions align with your PCB footprint design. Check RoHS3 compliance status if environmental regulations apply to your manufacturing process. Ensure the operating voltage range matches your system's power supply capabilities before integration.
Selection Notes
Select this component when a low-voltage, high-current brushed DC motor driver is required in a compact form factor. The 1.8V minimum supply voltage allows compatibility with battery-powered applications. Consider the 2A output capability relative to your motor's stall current requirements. The wide operating temperature range makes it suitable for diverse environmental conditions without additional cooling.
Part Context
This part belongs to Toshiba's series of integrated motor drivers designed for general-purpose applications. It combines control logic and power stages into a single semiconductor solution. The TC78H651 family targets markets needing reliable, space-efficient motor control without external discrete components. It serves as a direct interface between microcontrollers and brushed DC motors.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility and electrical specifications with alternative vendors before substitution.
