Maxim Integrated MAX14914 high-side switch

Specified for operation with supplies up to 40 V, the MAX14914 is a high-side/push-pull driver that operates as both an industrial digital output (DO) and an industrial digital input (DI).

Maxim-MAX14914-product-picture

Specified for operation with supplies up to 40 V, the MAX14914 is a high-side/push-pull driver that operates as both an industrial digital output (DO) and an industrial digital input (DI).
The high-side switch current is resistor settable from 135mA (min) to 1.3 A (min).
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 (active-low DOI_LVL-pin) for safety applications.
For DI operation, MAX14914 complies with Type 1, 2, or 3 input characteristics.
