TC78H620FNG

Overview

The TC78H620FNG,EL is a brushed DC motor driver IC manufactured by Toshiba Semiconductor and Storage. It utilizes DMOS technology to provide two half-bridge outputs capable of driving up to 1 A per channel. The device operates within a supply voltage range of 2.5 V to 15 V and features a low operating power consumption of 500 uA. It includes built-in protection circuits for over-current detection, thermal shutdown, and under-voltage lockout. The component is housed in an SSOP-16 package suitable for surface mount installation.

Feature Summary

• Integrates dual half-bridge outputs using DMOS technology for efficient brushed DC motor control
• Incorporates comprehensive protection mechanisms including over-current detection, thermal shutdown, and under-voltage lockout
• Designed for low power consumption with a standby current of 500 uA

Applications

• Brushed DC motor control in consumer electronics
• Fan speed regulation systems
• Small appliance motor drivers

Procurement Notes

Verify the specific ordering suffix (e.g., EL) against the manufacturer's datasheet to ensure correct packaging and tape specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the assembly process. Cross-reference the pinout diagram with the PCB layout to prevent interface mismatches during implementation.

Selection Notes

Select this component when a single-chip solution for dual brushed DC motors or one bipolar stepper motor is required within a 15 V system. It is appropriate for applications demanding low quiescent current and integrated protection features. Consider alternative models within the TC78H6 series if higher output current or different package constraints are necessary.

Part Context

This part belongs to the TC78H6 series of brushed motor driver ICs from Toshiba. These devices are silicon monolithic integrated circuits designed for low-profile applications. The series generally supports operation across a wide temperature range and offers various output current capabilities depending on the specific model variant selected.

Replacement Considerations

TC78H621FNG,EL: Offers 1.1 A output current in a 16-TSSOP package. TC78H630FNG,EL: Provides 2.1 A output current in a 16-TSSOP package.
