Toshiba Launches Dual H-Bridge Motor Driver IC With PWM Control
This H-bridge motor driver IC can deliver a PWM-controlled current of 2A.
Toshiba Electronics Europe GmbH (“Toshiba”) has further expanded its portfolio of driver solutions for brushed DC and stepper motors with the introduction of the TC78H660FNG. This 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 highly advantageous from a thermal management perspective, as there is considerably less heat that needs to be dissipated - thereby leading to system cost and space savings.
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. An array of safety features have 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.
