Description
Port2 PowerEnable; open collector output
(require external pull up resistor to properly
control power switch)
'0' = power on
'1' = power off
Port3 PowerEnable; open collector output
(require external pull up resistor to properly
control power switch)
'0' = power on
'1' = power off
Port3 Overcurrent; with internal pull up resistor;
8ms delay filter
'0' = overcurrent
'1' = not overcurrent
Port4 Overcurrent; with internal pull up resistor
8ms delay filter
'0' = overcurrent
'1' = not overcurrent
Port4 PowerEnable; open collector output
(require external pull up resistor to properly
control power switch)
'0' = power on
'1' = power off
Port4 Amber LED indicator; with internal pull up
resistor; open collector output.
'0' = LED on (Error condition)
