For applications in industrial automation, Maxim Integrated Products’ new MAX14900E is an eight-channel digital output switch controlled by an 8-bit parallel interface, or via a standard serial peripheral interface (SPI) which is also used for configuration and monitoring.
The eight digital channels require just 3 mA of supply current and the device operates from a wide supply range of 10 V to 36 V, making it compatible with the 24 V rail of many factory systems. With an input-to-output propagation delay of 0,3 μs, it can support fast switching rates of up to 100 kHz in push-pull configuration. On-resistance – a critical factor in static power dissipation – is just 85 m (typical) and 165 m (maximum).
Multiple devices can be daisy-chained to support additional I/O points via the single SPI interface, requiring only three isolators for all channels. The serial mode includes cyclic redundancy checking (CRC) for assured data integrity, as well as global and per-channel diagnostics for remote system monitoring. The chip can drive current loads up to 850 mA; outputs can be used in parallel to achieve higher drive current ratings. It is housed in a 48-pin, 7 x 7 mm QFN package.
Maxim offers both a complete reference design (MAXREFDES63#) as well as an evaluation kit with special prototyping features. The credit-card-sized reference design integrates the MAX14900E, a microcontroller, isolated I/O port, power supplies, UART and USB port.
