Quick Start
Required Equipment
● MAX14636/MAX14637EVkit
● Computer
● USB-A male to USB-B male cable
● USB-A male to micro-B USB male cable
● USB flash drive (optional)
Procedure
The EV kit is fully assembled and tested. Follow these
steps to verify board operation.
1) Verify that all jumpers are in their default positions.
2) Take USB-A male to USB-B male cable and connect
the cable to J3 from a computer.
3) Install a shunt on JP5. Verify LED4 is on.
4) Install a shunt on JP4. Verify LED5 is on.
5) Take USB-A male to micro-B USB male cable and
connect the cable to J2 from a computer. Verify LED1
and LED3 are on.
6) Optional: insert the USB flash drive in J1. Check
that the drive is accessible from computer. The drive
should enumerate and register in Windows.
7) Remove the USB flash drive and cable on J2.
Remove the shunts on JP4 and JP5.
8) Install a shunt on JP15. Verify LED14 is on.
9) Install a shunt on JP14. Verify LED15 is on.
10) Connect the micro-B USB cable to J5 from a
computer. Verify LED11 and LED13 are on.
11) Optional: insert the USB flash drive in J4. Check
that the drive is accessible from computer. The drive
should enumerate and register in Windows.
12) Remove USB flash drive and cable on J5. Remove
the shunts on JP14 and JP15.
Detailed Description of Hardware
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 surface-
mount 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.
MAX14637
LED11 SW_OPEN LED11 is on when MAX14637 SW_OPEN = low (switches are closed).
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.

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.
