MAX3051 Overview
Description
The MAX3051 interfaces between the CAN protocol controller and the physical wires of the bus lines in a controller area network (CAN). The MAX3051 provides differential transmit capability to the bus and differential receive capability to the CAN controller.
Key Features
- four different modes of operation: high-speed, slope-control, standby, and shutdown mode
- High-speed mode allows data rates up to 1Mbps
- The slope-control mode can be used to program the slew rate of the transmitter for data rates of up to 500kbps
- This reduces the effects of EMI, thus allowing the use of unshielded twisted or parallel cable
- In standby mode, the transmitter is shut off and the receiver is pulled high, placing the MAX3051 in low-current mode
- In shutdown mode, the transmitter and receiver are switched off
- The MAX3051 input common-mode range is from -7V to +12V, exceeding the ISO 11898 specification of -2V to +7V
- These features, and the programmable slew-rate limiting, make the part ideal for nonautomotive, harsh environments
- The MAX3051 is available in 8-pin SO and SOT23 packages and operates over the -40°C to +85°C extended temperature range
