DS1832S+T&R from Analog Devices Inc Maxim Integrated, in a SOIC-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 | PBRST | input | Pushbutton reset input that requires an active low signal; it is debounced internally and has an internal pull-up to VCC of 40 kΩ typical, and reset outputs are held active at least 250 ms after release. |
| 2 | TD | input | Time delay set pin: connect to GND for a 62.5 ms minimum watchdog timeout, leave floating for 250 ms minimum, or connect to VCC for 500 ms minimum. |
| 3 | TOL | input | Selects the VCC detect threshold: connected to GND the reset outputs trip below 2.98 V (2.80 V min to 2.97 V max), and connected to VCC they trip below 2.64 V (2.47 V min to 2.64 V max). |
| 4 | GND | power_in | Ground reference for all voltages on the device. |
| 5 | RST | output | Active-low reset output in push-pull form that stays valid down to 0.8 V VCC, and down to 0 V VCC when a ~100 kΩ pull-down resistor to ground is added. |
| 6 | RST | output | Active-high reset output (complement of the active-low RST) in push-pull form, driven active when VCC is out of tolerance, on a watchdog timeout, or on a pushbutton reset. |
| 7 | ST | input | Watchdog strobe input: a high-to-low transition must occur before the watchdog timeout to avoid a reset, the watchdog cannot be disabled, and the ST pulse width minimum is 20 ns. |
| 8 | VCC | power_in | Power supply input, 1.0 V minimum to 5.5 V maximum per the recommended DC operating conditions. |
