# XC6118N43AMR-G

**Torex Semicon** · Monitors & Reset Circuits · SOT-25

XC6118N43AMR-G from Torex Semicon, in a SOT-25. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VOUT | output | Output that goes Low when the sense voltage falls to the detect voltage; for the N-channel open drain version it needs a pull-up resistor, and absolute maximum output current is 10 mA with VOUT rated VSS-0.3 to 7.0 V. |
| 2 | VSS | power_in | Ground pin, the reference for all voltage ratings, with VIN rated VSS-0.3 to 7.0 V. |
| 3 | VIN | power_in | Supply input with an operating voltage range of 1.0 V to 6.0 V and an absolute maximum rating of VSS-0.3 to 7.0 V. |
| 4 | VSEN | input | Sense pin, separated from the supply so the IC can monitor another supply, with a voltage rating of VSS-0.3 to 7.0 V. |
| 5 | Cd | passive | Delay capacitance pin used to set the release delay time via an external capacitor, with a voltage rating of VSS-0.3 to VIN+0.3 V; leave open when the delay function is not used. |
