## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Voltage monitor and supply input connected to an internal high-value resistive divider; the output is pulled low if VIN falls below the UVLO threshold minus hysteresis, and output logic is not guaranteed below 1.2V. |
| 2 | NC | unconnected | No internal connection; this unconnected pin sits between high-voltage and low-voltage pins to help maintain PCB trace clearance. |
| 3 | NC | unconnected | No internal connection; this unconnected pin sits between high-voltage and low-voltage pins to help maintain PCB trace clearance. |
| 4 | NC | unconnected | No internal connection; this unconnected pin sits between high-voltage and low-voltage pins to help maintain PCB trace clearance. |
| 5 | NC | unconnected | No internal connection; this unconnected pin sits between high-voltage and low-voltage pins to help maintain PCB trace clearance. |
| 6 | REF | power_out | Buffered reference output at VREF with respect to GND; bypass with a maximum of 1nF unless a damping resistor is used. |
| 7 | INH | input | High comparator reference input whose voltage is multiplied by the range setting to set the VIN rising threshold; keep it within the common-mode range VCM (0.35V to 2.45V) or tie it to GND to enable built-in hysteresis. |
| 8 | INL | input | Low comparator reference input whose voltage is multiplied by the range setting to set the VIN falling threshold; keep it within VCM or tie it to GND to enable built-in hysteresis, since oscillation occurs if INL is greater than INH unless built-in hysteresis is enabled. |
| 9 | PS | input | Polarity select input; connect to REF or to a voltage above VTH for an inverting output with respect to VIN, or to GND for a noninverting output. |
| 10 | RS | input | Range select input; connect to GND for the 10x range (RS = L) or to REF for the 40x range (RS = H). |
| 11 | GND | power_in | Device ground, the reference for all voltages on the part. |
| 12 | NC | unconnected | No internal connection; this unconnected pin sits between high-voltage and low-voltage pins to help maintain PCB trace clearance. |
| 13 | NC | unconnected | No internal connection; this unconnected pin sits between high-voltage and low-voltage pins to help maintain PCB trace clearance. |
| 14 | NC | unconnected | No internal connection; this unconnected pin sits between high-voltage and low-voltage pins to help maintain PCB trace clearance. |
| 15 | NC | unconnected | No internal connection; this unconnected pin sits between high-voltage and low-voltage pins to help maintain PCB trace clearance. |
| 16 | OUT | output | Comparator output with a high-voltage active pull-down and a gated 500kΩ pull-up to an internal supply of 3.5V to 5V; it can be externally pulled up to 100V and is pulled low during UVLO. |
