请参考 PDF 数据表获取器件具体的封装图。
| PIN | TYPE | DESCRIPTION | ||
|---|---|---|---|---|
| NAME | DGS | DSG | ||
| ALERT | 3 | 3 | Digital output | Overlimit alert, active low, open-drain output |
| CMPIN | 8 | 6 | Analog input | Signal input to the comparator |
| CMPREF | 7 | 5 | Analog input | Input reference to the comparator |
| GND | 5 | — | Ground | Device ground. Connect the thermal pad to the system ground. See the layout example in Figure 54. |
| IN– | 10 | 8 | Analog input | Connect this pin to the load side of the shunt resistor |
| IN+ | 1 | 1 | Analog input | Connect this pin to the supply side of the shunt resistor |
| NC | 6 | — | — | Not internal connection to device. This pin can be left floating, grounded, or connected to the supply. |
| RESET | 4 | 4 | Digital input | Transparent or latch mode selection input. See the Alert Modes section for a detailed description on pin connections. |
| VOUT | 9 | 7 | Analog output | Current-sense amplifier output voltage |
| VS+ | 2 | 2 | Supply | Power supply: 2.7 V to 5.5 V |
| Thermal Pad | — | Thermal Pad | — | Ground reference for the device that is also the thermal pad used to conduct heat from the device. Tie this pad externally to ground. |
