14 ECLP External current limit peak

External voltage scales down the rated value. Voltage range: 0 V to 3.75 V (3.75 V = rated Ip) Refer to Section 4.2.

15	LMRET	Latch	Mode	Return for Latch Mode signals.
		return
16	GAIN	Current	gain	Shorting this pin to LMRET pin (J1/15) reduces
		change		the proportional gain of the current loop by 70%.
17	HARET	Hall	supply	Return used only for Hall supply.
		voltage return
18	HALL+	+5 V	Hall	+5 V supply voltage for Hall sensors.
	5V	supply voltage		Output current: maximum of 13 mA.
19	SORET	Status	output	Status output common AOK, SO1, SO2, SO3.
		return		Isolated from circuit common. See Figure 3-4.
20	SO2	Status output 2		Status indication output 2.
				Same specification as in pin J1/2.
21	SO3	Status output 3		Status indication output 3.
				Same specification as in pin J1/2.
22	EN-	Enable -		Negative voltage input of “Amplifier Enable” function.
				Optocoupler is isolated from the amplifier.
