The MAX14914, MAX14914A, and MAX14914B are a family of high-side/push-pull drivers that operate as both industrial digital outputs (DO) and industrial digital inputs (DI). The MAX14914 family features full IEC 61131-2 compliance in both their DO and DI modes of operation. The high-side switch current is resistor settable from 135mA (min) to 1.3A (min). The high-side driver’s on-resistance is 120mΩ (typ) at an ambient temperature of 125°C. Optional push-pull operation allows driving of cables and fast discharge of load capacitance. The output voltage is monitored and indicated through theDOI_LVLpin for safety applications.The MAX14914 family complies with Type 1, Type 2, or Type 3 input characteristics when configured for DI operation.The MAX14914A is a low-DOI-leakage version of the MAX14914, specifically designed to work together with the MAX22000 Industrial Configurable Analog IO device. The MAX14914B features a high-side switch overcurrent indication.ApplicationsConfigurable Digital Input/OutputIndustrial Digital Output and Input ModulesMotor ControlSafety Systems

The MAX14915 has eight high-side switches specified to deliver up to 700mA continuous current. The high-side switches have on-resistance of 250mΩ (max) at 125°C ambient temperature.The SPI interface has a built-in chip addressing decoder, allowing communication with multiple MAX14915s utilizing a common SPI chip select (active-low CS).The SPI interface provides flexibility for global and per-channel configuration and diagnostic, including over and undervoltage detection, open wire/load detection, overload and current limiting reporting, thermal conditions reporting, and more.Open load detection detects both open-wire/open-load conditions with switches in the on and off states. LED drivers provide indication of per-channel fault, status, and supply undervoltage conditions. Internal active clamps allow for fast turn-off of inductive loads.Integrated line-to-ground and line-to-line surge protection only requires a TVS on VDD.The MAX14915 is available in a compact 48-pin 6mm x 6mm QFN package.ApplicationsIndustrial Digital OutputsPLC Systems

The MAX14916 and MAX14916A are equipped with eight high-side switches with an on-resistance of only 120mΩ (typ), or 250mΩ (max) at 125°C ambient temperature. Each channel is specified to handle up to 1.1A (MAX14916) or 1.5A (MAX14916A) of continuous current. Similarly, two adjacent channels can be driven together to form four 2.4A (MAX14916) or 3A (MAX14916A) switches.The SPI interface has a built-in chip addressing decoder, allowing communication with up to four MAX14916 or MAX14916A devices utilizing a common SPI chip select (CS).The SPI interface provides flexibility for global and per-channel configuration and diagnostic, including undervoltage detection, open-wire detection, overload and current limiting reporting, thermal conditions reporting, and more.Each channel is equipped with open-wire detection that can detect an open-load in both switch on and off states. LED drivers provide indication of per-channel fault, status, and supply undervoltage conditions. Internal active clamps allow for fast turn-off of inductive loads.Integrated line-to-ground and line-to-line surge protection only requires a single TVS on VDD. Integrated surge protection works for quad and octal configuration.The MAX14916 and MAX14916A are available in a compact 48-pin 6mm x 6mm QFN package.ApplicationsIndustrial Digital OutputsPLC Systems
