Function
Ground and reference pin
Return line of the external unit, internally connected to GND via a line-protection transistor
Voltage-stabilized supply output and current-modulation input
Supply voltage of the IC
Voltage-stabilized supply output and current-modulation input
Smooth time constant for slow voltage change at both OUT pins
Return line of the external unit, internally connected to GND via a line-protection transistor
Ground and reference pin
Controls OUT1 voltage
ENABLE1 High = OUT1 active, ENABLE1 Low or open = OUT1 switched off
Current logic level output (low at high OUT2 current, monitoring via OCM2)
Analog current output, representing 1/10 current of OUT2
Analog current output, representing 1/10 current of OUT1
Current logic level output (low at high OUT1 current, monitoring via OCM1)
Controls OUT2 voltage
