The TDF1778 is a ZIP-11, ST-1778 monolithic integrated circuit made by STMicroelectronics. It is a quad half-bridge driver with inputs specifically designed for high voltage applications. This device can be used to drive four independent loads from a single power supply in applications such as DC brush and brushless motors, solenoid and relay actuators, stepping motors and more. It has a wide operating voltage range from 8 V to 36 V and can drive loads up to 3 A peak. The TDF1778 also has a high-level on-state resistance, low output-to-output cross conduction and high operating speed, making it an ideal choice for driving multiple loads.(For reference only)
