New H-bridge driver IC supporting low-voltage, large current drive

14-12-2018 | Toshiba | Semiconductors

Toshiba Electronics Europe has launched an addition to its line-up of dual H-bridge driver ICs for DC brushed motors and stepping motors. The new TC78H653FTG provides the low voltage (1.8V) and high current (4A) necessary for motor-based devices run by dry-cell batteries such as mobile devices, electronic goods for the home and USB drives.

The new driver IC is ideal for a broad range of applications including motor applications that are operated by relatively low voltage batteries in the range 1.8V to 7V, mobile devices with motors (electric toothbrushes, cameras, printers) using 3.7V lithium-ion batteries, home products, such as electronic locks, smart meters and toys using two 1.5V dry batteries, as well as products based on a 5V USB power supply.

The new device is housed in a tiny 3mm x 3mm QFN16 package that occupies less than one-third of the area of the previous solution, the TC78H651FNG.
