Analog Devices Inc Maxim Integrated · Supervisor And Reset ICs · SOT-23
DS1818R-10+T&R from Analog Devices Inc Maxim Integrated, in a SOT-23. 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 | RST | output | Active-low reset output with open-drain driver and an internal 5.5 kΩ pullup (3.5 kΩ to 7.5 kΩ); it asserts when VCC is out of tolerance, stays active for about 150 ms after VCC returns, and is also driven low by a pushbutton pull-low of at least 1 µs. |
| 2 | VCC | power_in | Power supply input monitored for out-of-tolerance conditions, with a 2.80 V to 2.97 V trip point for the -10 (10% tolerance) version and a supply range of 1.0 V to 5.5 V. |
| 3 | GND | power_in | Ground reference for the device; all voltages are referenced to ground. |
