J1, J3 GND: Supply ground terminal and load terminal

connection.

circuit or external supply.

J5 OUT: Load terminal connection.

Turrets Connected with Controller Pins and LEDs

Indicating Its State

DFLT, RED LED D2: Controller DFLT pin.

DSTAT, GREEN LED D3: Controller DSTAT pin.

FAULT, RED LED D4: Controller FAULT pin.

PWRGD, GREEN LED D5: Controller PWRGD pin.

Turrets Connected with Controller Pins and Other

UV: Controller UV pin.

OV: Controller OV pin.

EN: Controller EN pin.

DOFF: Controller DOFF pin.

PRI: Node for a prioritizer implementation.

GND and PROBE GND: Ground pins for instrumental

Jumpers

JP1, FB_SEL: Use 12V position for 12V rail operation

voltage; use 5V position for 5V rail operation voltage;

voltageregulationacrosstheMOSFETpowerterminal;use

OUT position for ideal diode MOSFET voltage regulation

across the series connected ideal diode MOSFET, sense

resistor, and Hot Swap MOSFET.

JP3, DSTAT_SEL: Use DOFF position to increase DSTAT

pin hysteresis from 20mV to 100mV (with 2.2k for R14,

R13 = 20k, R15 = 56.2k).

JP5,DEBOUNCE:Use100mspositionfor100msdebounce

time; use ADJ position for debounce time defined by

external capacitor C9.

JP6, RETRY: Use LATCH position to latch off after fault;

use RETRY position to try turning on again after a fault

with time off set by FTMR capacitor; if JP6 is not installed,

auto-retry duty cycle after a fault is less than 0.1%.

JP7, EN_SEL: Use EN position to connect controller EN

pin to GND; use DIS_EXT position to connect EN pin to

EN turret for external signaling.

JP8, DC_CFG: Use 1-DIODE position to regulate a diode

voltage across the ideal diode MOSFET; use 3-COMP

position to regulate a diode voltage across three compo-

nents (ideal diode MOSFET, sense resistor and Hot Swap

MOSFET).

JP9, DIODE_OFF: Use ON position to activate ideal diode

functionality; use OFF_EXT position to connect DOFF pin

to DOFF turret for external.
