Compact H-Bridge Driver IC for Low-Voltage 25V Drives

Toshiba Electronics Europe has announced an addition to its range of H-bridge [1] driver ICs for brushed DC and stepper motors. The TC78H620FNG is ideally suited to battery-powered mobile devices - such as fans and small printers - and home appliances.

The IC adopts a four-port interface control technique using the PHASE and ENABLE signals. Control is secured using just three ports, unlike previous devices that required all four ports for full step control of a stepper motor. This addresses challenges in applications where the lack of MCU control ports is an issue.

The TC78H620FNG is compatible with low-voltage drives (for motor drive: 2.5V and above, for logic control: 2.7V and above) making it suitable for mobile devices with a 3.7V lithium-ion battery drive. Either two DC brushed motors or a single stepping motor can be controlled. A maximum current consumption of 1uA in standby mode contributes to reduced power consumption.
