Dual channel H-bridge motor driver for USB and battery equipment

The TC78H660FNG H-bridge motor driver from Toshiba is suitable for mains, 5V USB and battery-powered equipment
Toshiba Electronics Europe has launched an H-bridge driver for brushed DC and stepper motors that can run from a 2.5V to 16V input voltage.

The TC78H660FNGH-bridge motor driver IC is based on the company’s latest generation DMOS process and can deliver a PWM-controlled current of 2A (maximum) to two brushed DC motors or a single stepper motor.

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

The 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 a low current requirement when in standby mode, drawing 0.1µA. An array of safety features has been incorporated. These include under-voltage lockout, over-current detection and thermal shut down.

The TC78H660FNG is available in a compact 5.0mm x 6.4mm TSSOP16 package.
