MAX14922 High-Side Switch Controller

Analog Devices MAX14922 High-Side Switch Controller is an N-channel FET controller for implementing a high-side switch that operates as an industrial digital output. The MAX14922 is specified for operation with supplies up to 70V. The controller features accurate, active current-limiting, with current defined by the R_S sense resistor connected between the V_DD and SNS inputs. The device is used with an external low R_ON FET, which acts as a load switch for industrial loads. High inductive clamping voltages can be achieved by connecting an external ground-connected TVS diode to the MAX14922 S input. The device features diagnostics such as load or supply-voltage monitoring, gate output ready, high voltage-supply indication, current limiting, current limit auto-retry timing, and overcurrent indication.
