24V dual-output industrial sensor transceiver

November 03, 2014 // By Graham Prophet
The MAX14836 transceiver is suitable for 24V binary sensors. A feature-rich dual sensor device, it has integrated LDOs and output voltage drop of under 1.8V Additional 24V digital inputs and outputs are provided. Two internal linear regulators generate common sensor power requirements: 5V and 3.3V.

On-board DIO and DO drivers are independently configurable for push-pull, high-side (pnp), or low-side (npn) operation. The device detects a wake-up condition and generates a wake-up signal on the active-low WU output.

An SPI interface allows configuration and monitoring of the devices. Extensive alarm conditions are detected and communicated through the active-low IRQ output and the SPI interface. The device features reverse-polarity, short-circuit, and thermal protection. All power lines are monitored for undervoltage conditions.

Both DIO and DO drivers are specified for sinking/sourcing 200 mA. The MAX14836 is available in a 4mm x 4mm, 24-pin TQFN package, and is specified over the -40°C to +105°C temperature range.
