24V Dual-Output Sensor Transceiver

The MAX14836 transceiver is suitable for 24V binary sensors. 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 200mA.

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.
