ON Semiconductor NCV7708DWR2 Hex Half-Bridge Driver

The ON Semiconductor NCV7708DWR2 is a versatile and robust hex half-bridge driver designed to handle a wide range of automotive and industrial applications. This integrated circuit (IC) is engineered to drive six independent half-bridge channels, making it an ideal solution for controlling small motors, lamps, and other inductive loads in your electrical systems.

The NCV7708DWR2 is characterized by its high level of integration, which includes features such as charge pump regulators, MOSFET drivers, and protection circuits. This integration simplifies the design process, reduces the number of external components required, and helps to minimize the overall system footprint. The device operates over a wide supply voltage range of 5.5V to 28V, ensuring compatibility with a variety of power systems.

Each half-bridge of the NCV7708DWR2 can be independently controlled via a standard SPI interface, which provides flexibility in managing the operation of the connected loads. The IC also includes diagnostic feedback through the same SPI interface, allowing for real-time monitoring and fault detection, which is critical for safety-critical applications.

Key features of the NCV7708DWR2 include:

• Operational voltage range from 5.5V to 28V
• Six high-current half-bridge drivers
• Integrated charge pump for high-side MOSFET gate drive
• Programmable PWM frequency and duty cycle
• Overcurrent, overtemperature, and undervoltage protection
• SPI interface for control and diagnostics
• Extended temperature range suitable for automotive environments (-40°C to 150°C)

With its robust design and comprehensive protection features, the NCV7708DWR2 ensures reliable operation even in harsh conditions. The IC's overcurrent protection includes current limitation and shutdown, while the overtemperature protection incorporates a thermal warning and thermal shutdown mechanism. Additionally, the undervoltage lockout feature ensures the device operates only when the supply voltage is within the specified range.

Whether you are designing automotive engine control units, body control modules, or industrial automation systems, the NCV7708DWR2 hex half-bridge driver from ON Semiconductor offers the performance, reliability, and functionality needed to drive your innovative solutions.
