# ADM6318CY29ARJZ-R7

**Analog Devices** · Monitors & Reset Circuits · SOT-23-5

ADM6318CY29ARJZ-R7 from Analog Devices, 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 | ~{RESET} | output | Active-low push-pull reset output, asserted whenever VCC is below the reset threshold VTH (guaranteed valid down to VCC = 1 V). |
| 2 | GND | power_in | Ground. |
| 3 | RESET | output | Active-high push-pull reset output (complement of the active-low RESET output on pin 1). |
| 4 | WDI | input | Watchdog input that generates a reset if the logic level stays low or high for the watchdog timeout, is cleared by a logic transition, and disables the timer when left floating. |
| 5 | VCC | power_in | Power supply voltage being monitored, operating range 1 V to 5.5 V (absolute maximum -0.3 V to +6 V). |
