MAX6751KA29+T from Maxim Integrated, in a SOT-23-8. 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 IN | input | High-impedance input to the adjustable reset comparator (threshold 1.235V typ); connect to the center point of an external resistor divider to set the monitored voltage threshold. |
| 2 | SWT | passive | Watchdog timeout input; a capacitor to ground sets tWD = 4.94 x 10^6 x CSWT (seconds, Farads), and connecting SWT to ground disables the watchdog timer. |
| 3 | SRT | passive | Reset timeout input; a capacitor from SRT to GND sets tRP = 4.94 x 10^6 x CSRT (seconds, Farads). |
| 4 | GND | power_in | Ground. |
| 5 | WDS | input | Watchdog select input; connect to ground for normal mode or to VCC for extended mode (basic timeout multiplied by 128), and a change of state clears the watchdog timer. |
| 6 | WDI | input | Watchdog input; a falling transition must occur within the selected watchdog timeout period or a reset pulse occurs, it must not be left floating, and a 100k resistor to ground is recommended when the watchdog is unused. |
| 7 | RESET | output | Open-drain active-low reset output (MAX6751) that asserts when VCC or RESET IN drops below its threshold or on a watchdog fault, and stays low for the reset timeout period after all reset conditions deassert; may be pulled up to 0 to 6V. |
| 8 | VCC | power_in | Supply voltage input and input for the fixed-threshold VCC monitor; operates from 1.0V to 5.5V (1.2V to 5.5V for TA = -40°C to 0°C). |
