Table 5-1 Pin Functions (VSON Package)
| PIN NO | PIN NAME | Type | DESCRIPTION | |
|---|---|---|---|---|
| TIOS102 | TIOS1023, TIOS1025 | |||
| 1 | VCC_IN | VCC_OUT | P | 3.3-V or 5-V linear regulator output; external 3.3-V or 5-V logic supply input for option without LDO. |
| 2 | NFAULT | NFAULT | O | Fault indicator output signal to the microcontroller. Connect this pin via pull-up resistor to VCC_IN (TIOS102) or VCC_OUT (TIOS1023, TIOS1025) |
| 3 | NC | NC | - | Do not connect to GND. Leave floating |
| 4 | IN | IN | 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. |
| 5 | EN | EN | I | Driver enable input signal from the local controller. Logic low sets the OUT 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 GND. |
| 7 | GND | GND | GND | Device ground connection |
| 8 | OUT | OUT | O | Driver output |
| 9 | VCC | VCC | P | Supply voltage (24 V nominal) |
| 10 | NC | NC | - | Do not connect to GND. Leave floating |
| Thermal Pad | Thermal Pad | — | Connect to GND plane for optimal thermal and electrical performance | |
