Toshiba Announces New Dual-Channel H-bridge Motor Driver IC with PWM Control

November 5, 2020 Tiera Oliver

Toshiba Electronics Europe has expanded its portfolio of driver solutions for brushed DC and stepper motors with the introduction of the TC78H660FNG. Per the company, the H-bridge motor driver IC, which is based on the company’s latest generation DMOS process, can deliver a PWM-controlled current of 2A (maximum). Running off a 2.5V to 16V input supply voltage, it can drive two brushed DC motors or a single stepper motor.

The on-resistance of this driver at typical operating conditions is just 0.48Ω. This is advantageous from a thermal management perspective, as there is less heat that needs to be dissipated.

The TC78H660FNG driver is suitable for a broad spectrum of potential applications, such as mobile devices running off a 3.7V Li-Ion battery and 5V USB-powered equipment, as well as 12V-rated household appliances. Supporting energy efficient operation, it has ultra-low current requirements when in standby mode, drawing 0.1µA. Safety features have also been incorporated. These include under-voltage lockout, over-current detection, and thermal shut down. Keeping PCB utilization to a minimum, this IC is supplied in a compact 5.0mm x 6.4mm TSSOP16 package.
