MAX14906 EVALUATION KIT AVAILABLE Quad-Channel Industrial Digital Output/Digital Input General Description The MAX14906 is an IEC 61131-2 compliant, high-speed, four-channel industrial digital output, digital input device that can be configured on a per-channel basis as a highside (HS) switch, push-pull (PP) driver, or a Type 1 and 3, or Type 2 digital input. The MAX14906 is specified for operation with a supply voltage up to 40V and is tolerant to 65V. The high-side switch current limiting is settable from 130mA to 1.2A with the option of 2x load inrush current. The high-side driver on-resistance is 120mΩ (typ) at 25°C ambient temperature. Optional push-pull operation allows high speed driving of cables and fast discharge of load capacitance. For digital input operation, current sinks for 2.3mA (Type 1 and 3) or 7mA (Type 2) are provided. The SPI interface has a built-in chip addressing decoder, allowing communication with multiple MAX14906 devices utilizing a shared SPI with a common chip select (CS). The SPI interface provides flexibility for global and per-channel configuration and diagnostics, including supply overvoltage and undervoltage detection, wire-break or openwire detection, thermal overload and current limit reporting, and more. For high-speed operation, the digital input and output states can be monitored and changed directly using pins for increased system speed and throughput. Open-wire...
