Timer/Dimmer with Gate Driver, Zero Detection & Protection
7. Pin description
VDD
q Power supply voltage, supply voltage for all internal circuits
q external block capacitor to be connected between this pin and ground
GND
q Supply voltage ground, ground reference point for all thresholds
OUT
q Gate Driver output
TRES
q Threshold input, to be connected with a cap and source resistance to set the reset time
INZ
q Zero crossing detection input
q Set the duty cycle when the voltage goes through zero
IOUT
q Current source output for soft start
CS
q Input, connected to a capacitor setting the soft start time
CM1, CM2
q Input, connection 1 and 2 for a cap, setting the pulse width via internal monoflop
OC1, OC2
q Current sense input for OCP, connection to external shunt resistors
q On over current conditions, the output OUT and status OS are both pulled low
OV
q Over voltage protection input, connected to an external diode with voltage divider
q On over voltage conditions, the output OUT and status OS are pulled low
OT
q Over temperature protection input, connected to an external NTC with voltage divider
q On over temperature conditions, the output OUT and status OS are pulled low
OS
q Output status indicator
q On over current, voltage and temperature conditions this output is pulled low
