The MAX14636/MAX14637 EV kit is a fully assembled and tested circuit board demonstrating the MAX14636 and MAX14637 charger detector ICs in a 10-pin surfacemount Ultra TQFN package. The EV kit circuit can be configured to evaluate the MAX14636 or the MAX14637 without an external power supply. There are LED indicators showing different logic outputs with different chargers attached. The EV kit also features a shorted USB path for board- and trace-only evaluation. Table 1. LED Indicator LED NAME DESCRIPTION MAX14636 LED1 SW_OPEN LED1 is on when MAX14636 SW_OPEN = low (switches are closed). LED2 CHG_DET LED2 is on when MAX14636 CHG_DET = high. LED3 CHG_AL_N LED3 is on when MAX14636 CHG_AL_N = low (VBUS is valid and charging is allowed). LED4 VHC_GOOD LED4 is on when VHC1 is powered. LED5 GOOD_BAT LED5 is on when MAX14636 GOOD_BAT is set to high. SW_OPEN LED11 is on when MAX14637 SW_OPEN = low (switches are closed). MAX14637 LED11 LED12 CHG_DET LED12 is on when MAX14637 CHG_DET = high. LED13 CHG_AL_N LED13 is on when MAX14637 CHG_AL_N = low (VBUS is valid and charging is allowed). LED14 VHC_GOOD LED14 is on when VHC2 is powered. LED15 GOOD_BAT LED15 is on when MAX14637 GOOD_BAT is set to high. www.maximintegrated.com Maxim Integrated 3 MAX14636/ MAX14637 Evaluation Kit Evaluates: MAX14636/MAX14637 USB Transceiver Power The EV kit features jumpers to select the power source for the USB transceiver side. Install shunts in below position to change the power source. Logic Power Use JP2, JP5, JP12, and JP15 to select power source for logic pins. They can be powered from the USB or external power supply. VBUS Use JP3 and JP13 to connect the VBUS pin to the VBUS of the micro-USB connector. GOOD_BAT Use JP4 and JP14 to connect GOOD_BAT to 3.3V or ground. LED5 or LED15 is on when GOOD_BAT is set high.
