MAX14882 Overview
Key Specifications
Pins: 16
Description
The MAX14882 isolated high-speed CAN transceiver improves communication and safety by integrating galvanic isolation between the CAN-protocol controller-side (TDX, RXD) of the device and the physical wires of the CAN network (CANH, CANL) cable-side/bus-side of the transceiver. Isolation improves communication by breaking ground loops and reduces noise where large differences in ground potentials exists between ports.
Key Features
- additional integrated protection for robust communication
- The ±25V receiver input commonmode range exceeds the ISO 11898 specification requirement of -2V to +7V
- The supply voltage range for the CAN bus-side of the device is 4.5V to 5.5V (VDDB)
- An integrated transformer driver and LDO can be used, with an external transformer, to generate the isolated supply for VDDB
- Field installation and troubleshooting are simplified by the polarity select (POL) input
