Power
- VIN / IN (terminal block) - To power the board, give it 3V to 22V DC. The power input pin is broken out at the bottom edge of the board (VIN) and on the terminal block on the left side of the board (IN).
- Vout / OUT (terminal block) - this is the output from the ideal diode. It is broken out at the bottom edge of the board (Vout) and on the terminal block on the right side of the board (OUT).
- GND / GND (terminal block) - common ground. The ground pin is broken out at the bottom edge of the board (GND) and on the terminal blocks on both sides of the board (GND).
LM73100 Pins
- UVLO - This is the active high enable pin. It is also used to set the undervoltage lockout threshold. At 3V, that is 1.2V and at 23V that is 9.2V.
- OVLO - This is the overvoltage lockout threshold pin. At 3V, that is 0.15V and at 23V it is 1.2V.
- PG - This is the power good indication pin. It is high when a proper power supply is detected.
- PGTH - This is the power good threshold pin. It can be set with a threshold setting to check against for the power good pin.
- DVDT - This is the slew rate/inrush current control pin.
- IMON - This is the current monitoring pin. You can read the analog voltage from this pin as a current monitor.
Power LED and Jumper
- Power LED - In the top center of the board, below the LM73100 label on the board silk, is the power LED, It is a green LED.
- LED jumper - This jumper is located on the back of the board and is labeled LED on the board silk. Cut the trace on this jumper to cut power to the power LED.
