The NCV7425DW5G is a driver, receiver, transceiver (DRT) especially designed to support hot plugging and wear leveling in low-voltage CAN systems. It is a flexible device with a low-power profile that is ideal for a wide range of applications.

With 2.7V to 5.5V supply voltage operation, this DRT provides the flexibility to accommodate different power supply design implementations. It features a differentially driven bus input that enables low-power standby or low-power consistancy during running mode. Additionally, the NCV7425DW5G has a low minimal power consumption in standby mode, resulting in optimal usage of power, when it is needed.

The NCV7425DW5G is optimized for CAN communication, and is specifically built to provide low-power operation with a wide range of bit rates, from 125 kbits/s up to 1Mbit/s in One-Shot operation.

The very low propagation delays for bus propagation are suitable for applications with low bit rate and timing requirements, improving the CAN communication performance. The integrated high-speed level shifters provide reliable speed and interface performance, with high Voltage level tolerance needs.

While the bus interface has a low-voltage Single-Ended (SE) configuration, the integrated ESD protection allows the device to handle external loads on the bus with an ESD protection of up to 2 kV.

The integrated protected internal receivers are designed to support bus-off mode, with the capability to detect error frames and to disable the driver stages according to protocol. This allows the driver stage to be shut off when a CAN bus error state is detected. The integrated short-to-power and short-to-ground protection protects both the transceiver from external transients.

The integrated receive and driver stages are controlled by the device status flow, which is a logic signal to detect the device’s state and select the corresponding stage. This allows the device to be powered-on or powered-off without generating any errors in the bus network.

The NCV7425DW5G’s modes of operation have been certified to comply with Automotive Electronics Council (AEC) Q100-002 revision C specifications, allowing for an improved design margin in automotive systems.

Furthermore, the device has an integrated sleep-mode detector, which monitors the signal edges on the bus, and when no edges occur it disables the device’s driver stage and enables the bus receiver. This way the device will automatically enter sleep-mode, reducing the power consumption for improved power efficiency.

The NCV7425DW5G is recommended for a range of automotive applications, such as body control-modules, occupant safety systems, and HVAC systems. It is also suitable for communication in industrial CAN networks, with applications in medical equipment and telecom power supplies, as well as general industrial applications.

The integrated coherent transient supressors provide additional protection against Electro-Static Discharges, making the NCV7425DW5G the right choice for controlling and protecting sensitive systems in the most rigorous operating environments.
