Evaluates: MAX14914/ MAX14914 Evaluation Kit MAX14914A/MAX14914B General Description Features The MAX14914 evaluation kit (EV kit) provides a prov- Robust Operation with Wide Range of Input Voltages en design to evaluate the MAX14914/MAX14914A/ and Load Conditions MAX14914B, configurable industrial digital output drivers/ -40C to +125C Temperature Range digital inputs. The EV kit allows controlling of the MAX14914 On-Board LED Indication of Status and Fault as either a digital output (in either High-Side or Push-Pull Conditions mode) or digital input with simple jumper settings. Reverse Supply Voltage Protection The EV kit must be powered from an external +24V power supply and can consume up to 1.3A (minimum) when fully Proven PCB Layout loaded. Fully Assembled and Tested The MAX14914EVKIT comes with a MAX14914ATE+ Ordering Information appears at end of data sheet. installed in a 16-pin, 4x4mm TQFN-EP package. MAX14914B overcurrent interrupt output is not directly supported. For the MAX14914B application refer to the MAX14914 IC data sheet.

Required Equipment 4) Move the J4 shunt to 1-2 position (IN = high). Observe MAX14914 EV kit that the DOI level becomes high and DS2 LED lights up. +24V power supply 5) Move the J4 shunt back to the 2-3 position (IN = low). Voltmeter 6) Move the J5 shunt to 1-2 position (PP = high, enable Function generator (optional) Push-Pull mode). Oscilloscope (optional) 7) Repeat steps 4 and 5 to verify that the DOI output and check that the DS2 LED follows the IN settings. Procedure 8) Move J3 shunt to 1-2 position (DI EN = high, enable DI The EV kit is fully assembled and tested. Follow the steps mode). Note that the shunts position of J4 is ignored. below to verify board operation: 9) Apply static 24V between TP11 (DOI) and TP12 1) Verify that all jumpers are in their default positions for (PGND). the digital output (DO), high-side operation (Table 1). 10) Observe that the DS2 LED follows the level of the DOI 2) Power up the EV kit with +24V from an external power input. supply.
