4.2.5 External
Resistor
Connect an external resistor between terminal J1/14 (ECLP) and terminal J1/8 (ECLRET).
The resistor value is given by:
The resistor value is given by:
0 < R
ECLP
< 36.4 K (1/8 Watt)
At RECLP greater than 36.4K, the current limit will be internally clamped to the nominal
value.
value.
IP(nom) is the nominal peak current limit of the amplifier.
4.2.6
Latch Mode (LM)
By connecting J1/7 to J1/15, the amplifier is latched to disable mode whenever a Short,
Commutation or Over Temperature failure occurs. Disabling the amplifier temporarily by
removing the power from Enable pin J1/1 resets the latch. Be sure to restore the Enable
connection when the reason for the event no longer exists.
