Toshiba TC78H651FNG H-bridge driver IC supporting low-voltage

The TC78H651FNG is a new dual H-bridge driver IC for DC brushed motors and stepping motors. It delivers performance at a low voltage (down to 1.8V) and high current (up to 1.6A) that is essential for equipment powered by dry-cell batteries. 

The new device is suitable for motor applications such as cameras and compact printers using 3.7V lithium-ion batteries, toys and home appliances, smart meters, and electronic locks using two 1.5V dry batteries, and devices using 5V USB power supplies.

Features

• Typical voltage range of a dual 1.5 cell or LiPo battery, down to 1.8V
• High current operation up to 1.6A
• Small package, SSOP16
• Saves board space
