Figure 5-1 DRV Package6-Pin WSONTop ViewTable 5-1 Pin Functions
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| EN | 4 | I | Logic-level control input. When is driven high, the power switch is enabled. When it is driven low, turn power switch off. This pin cannot be left floating and it must be limited below the absolute maximum rating if tied to VIN |
| FAULT | 3 | O | Active-low open-drain output, asserted during overcurrent, overvoltage or overtemperature. Connect a pull up resistor to the logic I/O voltage |
| GND | 5 | — | Ground connection; connect externally to PowerPAD |
| ILIM | 2 | O | External resistor used to set current-limit threshold; Recommended 33 kΩ ≤ RILIM ≤ 1100 kΩ |
| IN | 6 | I | Input voltage; connect a 0.1-μF or greater ceramic capacitor from IN to GND as close to the IC as possible |
| OUT | 1 | O | Protected power switch VOUT |
| PowerPAD™ | PAD | — | Internally connected to GND; used to heat-sink the part to the circuit board traces. Connect PowerPAD to GND terminal externally |
