Pin Functions
| PINS | I/O | DESCRIPTION | ||
|---|---|---|---|---|
| NAME | TPS24710/11 | TPS24712/13 | ||
| EN | 2 | 2 | I | Active-high enable input. Logic input. Connects to resistor divider. |
| FLT | – | 10 | O | Active-high, open-drain output indicates overload fault timer has turned MOSFET off. |
| FLTb | 10 | – | Active-low, open-drain output indicates overload fault timer has turned MOSFET off. | |
| GATE | 7 | 7 | O | Gate driver output for external MOSFET |
| GND | 5 | 5 | – | Ground |
| OUT | 6 | 6 | I | Output voltage sensor for monitoring MOSFET power. |
| PG | – | 1 | O | Active-high, open-drain power good indicator. Status is determined by the voltage across the MOSFET. |
| PGb | 1 | – | Active-low, open-drain power good indicator. Status is determined by the voltage across the MOSFET. | |
| PROG | 3 | 3 | I | Power-limiting programming pin. A resistor from this pin to GND sets the maximum power dissipation for the FET. |
| SENSE | 8 | 8 | I | Current sensing input for resistor shunt from VCC to SENSE. |
| TIMER | 4 | 4 | I/O | A capacitor connected from this pin to GND provides a fault timing function. |
| VCC | 9 | 9 | I | Input-voltage sense and power supply |
