Evaluates: MAX17610 4.5V to 60V, 1A, MAX17610 Evaluation Kit Reverse-Voltage Protector with Forward Current Limit General Description Quick Start The MAX17610 evaluation kit (EV kit) is a fully assembled Recommended Equipment and tested circuit board that demonstrates the MAX17610 MAX17610 EV kit 4.5V to 60V, 1A, reverse-voltage protector with forward 60V DC power supply current-limit in a 12-pin TDFN-EP package. The EV kit can be configured to demonstrate different current-limit Multimeters types, and different current-limit thresholds. Adjustable load (0A to 1.5A) USB-A male to USB-B male cable or 5V DC power Features supply 4.5V to 60V Operating-Voltage Range Equipment Setup and Test Procedure Features a TVS Diode across the Input and Schottky Diode across the Output Terminals The EV kit is fully assembled and tested. Follow the steps below to verify board operation. Evaluates Three Current-Limit Types, and Current- Limit Threshold Caution: Do not turn on the power supply until all connections are completed. Internal UVLO set to 4V 1) Verify that all jumpers are in their default positions. Jumper-Configurable Current-Limit (Selected as 0.1A 2) Connect the USB cable to J1 from a computer or by default) connect a 5V-DC power supply to TP3. Current-Limit Mode Set To Autoretry by default 3) Verify that LED1 is on. Proven PCB Layout 4) Set the 60V DC power supply to 5V and connect to IN (J2/TP6). Verify that OUT (J3/TP8) is 5V. Fully Assembled and Tested 5) Set the DC power-supply voltage to 24V and con- nect the adjustable load between OUT and GND terminals and a multimeter in series to measure the current. Gradually increase the load current and verify that the OUT goes down and FWD goes low when the load current increases above 0.1A. 6) The jumper JU1 can be configured to change the Ordering Information appears at end of data sheet. current limit as given in Table 2. Verify various cur- rent limit operations by repeating step 5. CAUTION: When applying a negative input to V , the IN negative input test should be performed when the output capacitors are fully discharged and V is not supplied.

The EV kit circuit can be configured to evaluate the overcurrent threshold by external resistors connected to Enable the SETI pin and is jumper-configurable through jumper To enable the device, connect a USB-A male connector JU1. Using jumper JU4, the EV kit circuit can be config - from the computer to the USB-B female connector, J1, or ured to evaluate different current limit types (Autoretry, an external 5V supply to TP3 and GND. This provides 5V Continuous, and Latch-off). LED1 on the EV kit indicates to V and to the EN pin (JU5 connects V to EN BUS BUS availability of logic power for annunciation signals (FWD by default).

The EV kit provides on-board output capacitors to enable Current-Limit Threshold a demonstration of the MAX17610 protection features. The EV kit features a jumper (JU1) to select the current- Input-Power Supply limit threshold. Install a jumper as shown in Table 2 to The EV kit is powered by a user-supplied 4.5V to 60V change the current-limit threshold. Table 1.
