Designed to meet the modern requirements of mains-, 5V USB-, and battery-powered equipment

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.
