Table 5-1 Pin Functions (VSON Package)
| PIN NO | PIN NAME | TYPE | DESCRIPTION | |
|---|---|---|---|---|
| TIOL112 | TIOL1123 TIOL1125 | |||
| 1 | VCC_IN | VCC_OUT | P | VCC_IN (TIOL112): External 3.3-V or 5-V logic supply input pin. VCC_OUT (TIOL1123, TIOL1125): 3.3-V or 5-V linear regulator output |
| 2 | NFAULT | NFAULT | O | Fault indicator output signal to the microcontroller. A low level indicates either an over- current, an undervoltage supply or an overtemperature condition. |
| 3 | RX | RX | O | Receive data output to the local microcontroller |
| 4 | TX | TX | I | Transmit data input from the local microcontroller. No effect if EN is low. Logic high sets low-side switch. Logic low sets high-side switch. Weak internal pull-up. |
| 5 | EN | EN | I | Driver enable input signal from the local microcontroller. Logic low sets the CQ output at Hi-Z. Weak internal pull-down. |
| 6 | ILIM_ADJ | ILIM_ADJ | I | Input for current limit adjustment. Connect resistor RSET between ILIM_ADJ and L-. |
| 7 | L- | L- | GND | IO-Link ground potential |
| 8 | CQ | CQ | I/O | IO-Link data signal (bidirectional) |
| 9 | L+ | L+ | P | IO-Link supply voltage (24 V nominal) |
| 10 | WAKE | WAKE | O | Wake-up indicator to the local microcontroller. Open-drain output, connect this pin via pull-up resistor to VCC_IN/OUT. |
| Thermal Pad | Thermal Pad | — | Connect to L- for optimal thermal and electrical performance | |
