The MAX14914 is a high-side/p ush-pull driver that operates as both an industrial digital output (DO) and an industrial digital input (DI). The MAX14914 is specified for operation with supplies up to 40V. 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 125°C ambient temperature. Optional push-pull operation allows driving of cables and fast discharge of load capacitance. The output voltage is monitored and indicated through the active-low DOI_LVL pin for safety applications.

The MAX14914 complies with Type 1, Type 2, or Type 3 input characteristics when configured for DI operation.
