Pin	Short	Function		Description
#	Form
1	EN+	Enable +		Positive voltage input of the “Amplifier Enable” function.
				To enable operation of the amplifier, the optocoupler
				must be energized by applying voltage between this pin
				(+) and pin J1/22 (-).
				The optocoupler is isolated from the amplifier. See Figure
				3-4.
				“OFF” voltage: 0 V < Vin < 1 V.
				“ON” voltage: 2.5 V < Vin < 10 V, 5 V typically with
				current consumption 2.5 mA.
2	AOK	Amplifier OK		When the amplifier is under normal operating conditions,
				this output is in the “active low“ state. When a failure
				occurs, this output is changed to the “open” state.
				The optocoupler is an isolated, open collector NPN type.
				See Figure 3-4.
				Maximum voltage = 30 V
				Maximum current = 8 mA
				“On” voltage: V OUT(On) < 0.8 V
				Refer to Section 4.4.
3	SO1	Status output 1		Specifications same as in pin J1/2.
4	HA	Hall A input		Logic levels: TTL
				Maximum input voltage: 15 VDC.
5	HB	Hall B input		Logic levels: TTL
				Maximum input voltage: 15 VDC.
6	HC	Hall C input		Logic levels: TTL.
				Maximum input voltage: 15 VDC.
7	LATCH	Latch mode		Latch mode input. For more details see the Latch Mode
				section in Chapter 4.
8	ECLRET	Current	limits	Current limit signals return.
		return
9	ECLC	External	limit	External voltage scales down the rated value.
		current		Voltage range: 0 V to 3.75 V (3.75 V = rated Ic)
		continuous
				Refer to Section 4.3.
10	CM	Current		Analog output with a scale of ± 3.9 V for ± Ip.
		monitor		Output resistance: 1 kΩ
11	CREF+	Current		Positive input of a differential amplifier:
		command		Input operating voltage range: ±3.75 V
		positive
				Maximum input voltage: ±20 V
				Maximum common mode voltage: ±6 V
				Differential input impedance: 40 kΩ
				Refer to Section 4.2.
12	CREF-	Current		Negative input of a differential amplifier.
		command		Same specification as in pin J1/11.
		negative
13	CMRET	Current		Current monitor (CM) signal return.
