SGM823-SXN5G from SGMICRO, in a SOT-23-5. 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 | nRESET | output | Active-low push-pull reset output that delivers a 200ms (TYP) low pulse and stays low while VCC is below the reset threshold or nMR is low; absolute maximum output current is 20mA. |
| 2 | GND | power_in | Ground reference pin; absolute maximum GND input current is 20mA. |
| 3 | nMR | input | Active-low manual reset input with an internal 59kΩ pull-up (44kΩ to 78kΩ), VIL maximum 0.8V and VIH minimum 2V, drivable by CMOS/TTL logic or a switch to GND, and may be left open or tied to VCC if unused. |
| 4 | WDI | input | Watchdog input that must toggle within the watchdog timeout (1.6s TYP, 1.1s to 2.4s) or a reset is triggered; the watchdog is disabled when WDI is left open or driven by a three-stated buffer. |
| 5 | VCC | power_in | Supply voltage pin with an operating range of 1V to 5.5V and an absolute maximum range of -0.3V to 6.0V. |
