MAX823TEUK+T from Analog Devices Inc Maxim Integrated, 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 reset output that stays low whenever VCC is below the reset threshold or MR is logic low, and for 200ms (tRP) after VCC rises above threshold, a watchdog reset, or MR returns high; it is guaranteed to be in the correct state for VCC down to 1V and both sources and sinks current (800µA max source for L/M, 400µA for T/S/R/Z/Y). |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | MR | input | Manual reset input where a logic low asserts reset and reset stays asserted while MR is low and for 200ms after it returns high, with an internal 35-75kΩ (52kΩ typical) pullup so it may be left open or tied to VCC when unused. |
| 4 | WDI | input | Watchdog input that must toggle within the watchdog timeout period (1.12s min, 1.60s typ, 2.40s max) or reset is asserted, with the timer cleared by reset or any WDI edge; leaving WDI unconnected or three-stated disables the watchdog, and WDI input current is limited to 160µA maximum when driven high. |
| 5 | VCC | power_in | Supply voltage input, specified for +3.15V to +3.6V for the MAX823T suffix with absolute maximum rating of -0.3V to +6.0V. |
