Evaluates: MAX14922 MAX14922 Evaluation Kit General Description Quick Start The MAX14922 evaluation kit (EV kit) provides a proven Required Equipment design to evaluate the MAX14922 industrial-grade high- MAX14922 EV kit side switch controller for ground connected resistive, Up to +60V DC power supply inductive, and capacitive loads with diagnostics. Optional +2.5V to +5.5V DC power supply The MAX14922 EV kit must be powered from an external +24V power supply and can draw more than 10A when Optional signal generator fully loaded. Load The EV kit PCB comes with the MAX14922ATE+ Procedure (16 TQFN, 3mm x 3mm) device installed, and includes The EV kit is fully assembled and tested. Follow the steps Si7322DN, n-channel FET and PCB space for a power FET in a TO-252/DPAK/SOT428 package, enabling easy below to verify board operation: and simple evaluation of the device with loads. 1) Verify that all jumpers are in default positions (Table 1). Features 2) Connect the EV kit to the external DC power supply Robust Operation with Wide Range of Input Voltages through V banana plugs. Do not turn on the power DD and Load Conditions supply. Safety and Protection Device Included for +24V 3) Connect the load through LOAD banana plug and Supply Evaluation with Up To 1.2kV IEC 61000-4-5 connect the load return to the GND (ground return) at Source to Ground banana plug. Fast Inductive Load Demagnetization 4) Verify shunt positions for required operation. LED Indication of Status and Fault Conditions 5) The default shunt position on J1 connects the internal Overvoltage 5V output to the logic supply V input. An external 5V L Overcurrent supply is not required in this case. Ready 6) The default shunt position on J4 ties the IN input to Thermal warning Fault Condition Indication 5V, forcing the Gate high to turn on the external FET.

MAX14922 EV Kit Shunt Positions and Settings HEADER SHUNT POSITION FUNCTION DESCRIPTION 1-2* V 5V output connected to V logic supply input. 5 L J1 Not Installed V logic supply must be externally provided using the V connector. L LOGIC Connects LO logic output to the pull-down resistor and RED fault indication LED. 1-2 Use when undervoltage V / LOAD-output detection is needed. DD Populate R5, R6, and R7 resistors appropriately. J2 Disconnects the pull-down resistor. LED not in use. Use this mode when the V /LOAD- DD Not Installed* detection function is not in use (R5, R6, and R7 resistors are DNI/default mode). Connects the RDY logic output to the pull-up resistor and RED fault indication LED. The 1-2* RDY status output indicates RED when the Gate output of MAX14922 is forced off, turning J3 the external switch OFF. This indicates fault. Not Installed Disconnects the pull-up resistor. The fault indication function is not in use. 1-2* IN input is pulled High. Turns-on the FET. J4 IN input is pulled low by R4 pull-down resistor. Not Installed Use J12 BNC input to apply toggling input from signal generator to turn on/off external FET . J5 V to external FETs drain test point or V DD DRAIN J6 Gate test point J7 Load/Source test point Not Installed* The COMP input is left unconnected. Connects the V /DRAIN to the COMP input. Choose R5 and R6 resistors appropriately DD 1-2 to reduce power dissipation. J8 Connects the SOURCE to the COMP input. Choose R5 and R7 resistors appropriately to 2-3 reduce power dissipation. Connects OV logic output to pull-up resistor and RED fault indication LED. 1-2* Overvoltage at V /Drain turns on RED LED indicating fault. J9 DD Not Installed Disconnects the pull-up resistor. The fault indication function is not in use. Connects THW logic output to the pull-up resistor and RED fault indication LED. 1-2* Thermal warning indication turns on RED LED. J10 Not Installed Disconnects the pull-up resistor. The fault indication function is not in use Connects the OVCURR logic output to the pull-up resistor and RED fault indication LED. 1-2* The overcurrent indication turns on the RED LED. J11 Not Installed Disconnects the pull-up resistor. The fault indication function is not in use. *Default position. Maxim Integrated 2 www.maximintegrated.com
