Logic translators and level shifters bridge two different logic families for communication. The SN65EPT21DR is an advanced chipset intended for select device level shifters and bus buffering applications. In many cases, vehicle cabling systems use two different logic families. This product bridges the mismatch.

The SN65EPT21DR is a dedicated device used for level shifting in applications with a large current draw. By changing the logic level of the input signal, the device can be used between the low-side power driver and the CAN data line. This lets the CAN line operate correctly while keeping the minimum common ground potential between the two nodes.

The SN65EPT21DR has a low-side driver (high-side) and a low-side power driver (low-side). The low-side driver acts as a logic level shifter, while the low-side power driver can handle up to 1A. The device has a wide level-shifting range, with compatibility up to 3.3V (referenced to ground).

The SN65EPT21DR includes a CAN transceiver that supports the CAN 2.0A and CAN 2.0B protocol. It can also be used in a variety of different network configurations. The device is powered from a 5V logic supply, and provides 5V support for all logic inputs. The differential data handling of the CAN transceiver makes it ideal for CAN bus communication applications.

The SN65EPT21DR is a power management device, utilizing programmable output levels. The output waveforms can be configured to reduce overall peak power requirements and closely follow the microcontroller\'s power supply voltage. This helps protect components against potential damage or faulty operation caused by large transient currents.

The SN65EPT21DR is a dual-channel, switched capacitor-based level shifter. It works by outputting two voltage levels to the logic receiving device, which in turn outputs them to the device it is intended to shift the logic levels for. This allows for the level shifting process to be efficient, quick, and accurate. Additionally, the two-line voltage control enables the device to switch back and forth efficiently between different logic level voltages.

The SN65EPT21DR is an ideal solution for CAN bus level shifting applications. Its differential data handling capability, low-power operating mode, and power management features make it an excellent choice for high-speed, low-power-consumption electronics systems. This device is specifically designed to provide power and data handling solutions in OEM applications where signal integrity and accuracy are paramount.
