MAX823SEUK+T from Analog Devices Inc Maxim Integrated, in a SOT-23-5L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RESET | output | Active-low reset output (push-pull); asserts low when VCC falls below the 2.93V threshold or MR is driven low, remains asserted for 200ms (typ, 140ms min) after VCC recovers; VOL ≤ 0.3V at ISINK = 1.2mA, VOH ≥ 0.8×VCC at ISOURCE = 30µA, guaranteed valid to VCC = 1V; ISOURCE short-circuit max 400µA. |
| 2 | GND | power_in | Ground; all voltages referenced to this pin; supply current 5µA (typ), 12µA (max) for MAX823S in SOT23 with WDI and MR unconnected. |
| 3 | MR | input | Active-low manual reset input with internal 35-75kΩ (typ 52kΩ) pullup to VCC; VIL ≤ 0.3×VCC, VIH ≥ 0.7×VCC; asserts RESET while held low and for 200ms after returning high; MR pulse width ≥ 1µs required; noise-immune to pulses ≤ 100ns; leave open or connect to VCC if unused. |
| 4 | WDI | input | Watchdog input; reset asserts if WDI remains continuously high or low beyond the watchdog timeout period (1.12s min, 1.60s typ, 2.40s max); timer cleared on any rising or falling edge or on RESET assertion; VIL ≤ 0.3×VCC, VIH ≥ 0.7×VCC; minimum pulse width 50ns; leave unconnected or tri-state driver to disable watchdog. |
| 5 | VCC | power_in | Positive supply voltage; operating range 1.0V to 5.5V (for MAX823S nominal range 3.0V to 3.6V per reset threshold); supply current 5µA (typ), 12µA (max) for MAX823T/S/R in SOT23; decouple with 0.1µF capacitor close to pin for transient immunity. |
