4.5.2External Resistor

Connect an external resistor between terminal J2/3 (ECLP) and terminal J2/2 (ECLRET). The resistor value is given by:

RECLP (Kohm) = 12.5 * Ip(new) - 1

Ip(nom)

0 < RECLP < 11.4 K (1/8 Watt)

At RECLP greater than 11.4K, the current limit will be internally clamped to the nominal value.

IP(nom) is the nominal peak current limit of the amplifier.

4.6Latch Mode (LM)

By connecting J2/7 to J2/8, the amplifier can be latched to Disable mode whenever a Short or Over Temperature failure occurs. Disabling the amplifier temporarily (removing the power from Enable pins J2/9 and J2/10) resets the latch. Be sure to restore the Enable connection when the reason for the event no longer exists. For permanent selection, a simple short is recommended. For remote selection, use the following scheme.

4.7Amplifier Enable Logic

Pins J2/9 and J2/10 are the inputs of an opto-coupler, which must be energized to enable operation of the amplifier. If the Enable input is kept high before turning on the amplifier, the amplifier power output will be active immediately upon power on.
