Pin Functions

PIN DESCRIPTION
NAME NUMBER TYPE(1)
IO-Link Interface
L+ 10 P IO-Link supply voltage (24V nominal)
CQ 12 I/O IO-Link data signal (bi-directional)
L– 14 P IO-Link ground (connect to board ground)
Local Controller Interface
CUR_OK 15 OD High-CQ-current fault indicator output signal from PHY to the microcontroller. Connect this pin via pull-up resistor to Vcc OUT. A LOW level indicates over-current condition.
WAKE 16 OD Wake up indicator from the PHY to the local controller Connect this pin via pull-up resistor to Vcc OUT.
RX 17 O PHY receive data output to the local controller
TX 18 I PHY transmit data input from the local controller
EN 20 I Driver enable input signal from the local controller
Power Supply Pins
VCC IN 7 A Voltage supply input for SN65HVD102
Voltage sense feedback input for the voltage regulator of the SN65HVD101. Connect this pin to pin 8 either directly or through a current boost transistor.
VCC OUT 8 P Not connected in SN65HVD102
Linear regulator output of SN65HVD101. Connect this pin to pin 7 either directly or through a current boost transistor.
GND 3, 6, 13 P Logic ground potential
Special Connect Pins
VCC SET 1 I Connect this pin to ground to make Vcc OUT = 3.3V. Leave this pin floating to make Vcc OUT = 5V.
ILIMADJ 4 A Input for current limit adjustment. Connect resistor RSET between this pin and ground. For RSET values see Figure 2.
PWR_OK 5 OD Power-Good indicator. Connect this pin via pull-up resistor to Vcc OUT. A HIGH at this pin indicates that L+ and Vcc OUT are at correct levels.
Temp_OK 19 OD Temperature-Good indicator. Connect this pin via pull-up resistor to Vcc OUT. High-impedance at this pin indicates that the internal temperature is at a safe level. A low at this pin indicates the device is approaching thermal shutdown.
NC 2, 9, 11 – No Connection. Leave these pins floating (open)
