MAX14653–MAX14655 Evaluation Kits General Description The MAX14653–MAX14655 evaluation kits (EV kits) are fully assembled and tested circuit boards that demonstrate the functionality of the MAX14653– MAX14655 high-current overvoltage protectors with adjustable OVLO in a 12-bump wafer-level package (WLP). Each EV kit features a jumper for selecting the preset OVLO threshold or the external resistor-divider for the adjustable OVLO threshold. Input power to the EV kits is provided by external supplies.

Quick Start Required Equipment ● MAX14653–MAX14655 EV kit ● 5V power supply ● Variable power supply Procedure The EV kits are fully assembled and tested. Follow the steps below to verify board operation and begin evaluation: 1)Verify that a shunt is installed across pins 2-3 on jumper J1 for evaluation of preset overvoltage threshold or that a shunt is installed across pins 1-2 of J1 for evaluation of external resistor-divider-set threshold. Refer to the MAX14653 /MAX14654/MAX14655 IC data sheet for instructions on how to select external resistors R1 and R2. 2)Verify that a shunt is installed across pins 1-2 on jumper J2 to enable LED1. LED1 glows green when ACOK goes low indicating no fault condition on IN. 4) Connect the variable power supply set to 2.5V minimum to VIN. 5) Evaluate the device by increasing the power supply above the OVP threshold, as defined by the setup. Detailed Description of Hardware The MAX14653–MAX14655 EV kits are fully assembled and tested circuit boards that demonstrate the functionality of the MAX14653–MAX14655 high-current overvoltage protectors with adjustable OVLO in a 12-bump WLP. Each EV kit features a jumper for selecting the preset OVLO threshold or the external resistor-divider for the adjustable OVLO threshold. Input power to the EV kit is provided by external supplies. The EV kit’s PCB is designed with 1oz copper. Power Supply Each EV kit is powered by a user-supplied 4.5V to 5.5V DC power supply connected between VCC and GND, as well as a variable 2.5V minimum DC power supply connected between VIN and GND. 3) Connect the 5V power supply at the EV kit’s VCC test point to power the ACOK LED indicator circuit. www.maximintegrated.com Maxim Integrated │ 2 MAX14653–MAX14655 Evaluation Kits ACOK Indicator LED Each EV kit features a peripheral circuit that gives visual indication of no fault at VIN. Simply install the shunt on jumper J2 to connect the peripheral circuit to the ACOK output of the device. See Table 1 for jumper settings. OVP Threshold Each EV kit features a jumper to change the overvoltage threshold of the device between preset threshold mode and adjustable threshold mode, in which the threshold is Evaluate: MAX14653–MAX14655 set by an external resistor-divider connected at OVLO. To use the device in preset threshold mode, simply connect a shunt across pins 2-3 on jumper J1. For adjustable threshold mode, connect a shunt across pins 1-2 on J1. Refer to the MAX14653/MAX14654/MAX14655 IC data sheet for information on how to set the adjustable threshold using resistors R1 and R2. See Table 1 for jumper settings. Table 1.
