PRODUCTION DATA.
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) |
