PRODUCTION DATA.
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| IO-Link Interface | |||
| CQ | 8 | I/O | IO-Link data signal (bidirectional) |
| L+ | 9 | POWER | IO-Link supply voltage (24 V nominal) |
| L- | 7 | POWER | IO-Link ground potential |
| Local Controller Interface | |||
| EN | 5 | I | Driver enable input signal from the local controller. Logic low sets the CQ output at Hi-Z. Weak internal pull-down. |
| WAKE | 10 | OPEN-DRAIN | Wake up indicator to the local controller. Connect this pin via pull-up resistor to VCC_IN/OUT. |
| RX | 3 | O | Receive data output to the local controller |
| TX | 4 | I | Transmit data input from the local controller. No effect if EN is low. Logic high sets low-side switch. Logic low sets high-side switch. Weak internal pull-up. |
| Thermal Pad | — | — | Connect to L- for optimal thermal and electrical performance |
| Internal LDO | |||
| VCC_IN/OUT | 1 | POWER | 3.3-V or 5-V linear regulator output; external 3.3-V or 5-V logic supply for option without LDO. |
| Special Connect Pins | |||
| ILIM_ADJ | 6 | I | Input for current limit adjustment. Connect resistor RSET between ILIM_ADJ and L-. |
| NFAULT | 2 | OPEN-DRAIN | Fault indicator output signal to the microcontroller. A low level indicates either an over- current, an undervoltage supply or an overtemperature condition. |
