TC78H660FNG,EL

Overview

The TC78H660FNG,EL is a dual-channel brushed DC motor controller and driver manufactured by Toshiba Semiconductor and Storage. It utilizes DMOS technology to provide independent control for two channels, each capable of delivering up to 2A output current. The device operates within a supply voltage range of 2.5V to 16V and supports PWM input signals with a maximum frequency of 400 kHz. Designed for surface-mount installation, it is housed in a TSSOP-16 package. The component functions as a half-bridge driver configuration, integrating necessary control logic and power stages into a single integrated circuit suitable for compact motion control applications.

Feature Summary

• Dual-channel architecture providing independent control over two separate brushed DC motors
• Integrated DMOS half-bridge power stage eliminating the need for external discrete components
• Supports Pulse Width Modulation (PWM) input signals for precise speed regulation
• Includes built-in protection mechanisms such as thermal shutdown and under-voltage lockout

Applications

• Small household appliances requiring dual-motor control
• Portable robotic devices and automated toys
• Automated office equipment such as printers or scanners
• Battery-powered mobile platforms and wheeled robots

Procurement Notes

Verify the specific suffix EL against the official Toshiba datasheet to confirm packaging and tape-and-reel specifications. Ensure that the operating voltage requirements of the target application fall within the 2.5V to 16V range. Confirm that the thermal management design can handle the power dissipation characteristics specified in the technical documentation. Cross-reference the TSSOP-16 footprint dimensions with the PCB layout guidelines provided in the manufacturer's data sheet to ensure mechanical compatibility.

Selection Notes

Select this component when a dual-channel solution is required for low-to-medium current brushed DC motor applications. The 2A per channel rating suits small motors found in consumer electronics. Consider the TSSOP-16 package size if board space is limited compared to larger packages. Evaluate the 400 kHz PWM frequency limit against the system's control loop requirements. This part is appropriate for designs needing integrated protection features without adding complex external circuitry.

Part Context

This component belongs to the TC78H6xx series of motor drivers from Toshiba Semiconductor and Storage. The series offers various configurations tailored for different motor types and current requirements. The FNG suffix typically denotes the TSSOP-16 package variant, distinguishing it from other form factors like VQFN available in the same product family. It serves as a specialized PMIC solution for motion control tasks.

Replacement Considerations

Consult the official Toshiba cross-reference list for verified substitutes. Potential alternatives may include other models within the TC78H6xx series with adjusted current ratings or package types. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
