Description
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
Return for Latch Mode signals.
16 GAIN Current gain
change
Shorting this pin to LMRET pin (J1/15) reduces
the proportional gain of the current loop by 70%.
17 HARET Hall supply
voltage return
Return used only for Hall supply.
18 HALL+
5V
+5 V Hall
supply voltage
+5 V supply voltage for Hall sensors.
Output current: maximum of 13 mA.
19 SORET Status output
return
Status output common AOK, SO1, SO2, SO3.
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.
