STMicroelectronics · Supervisor And Reset ICs · SOT-23-6
STM6719TWWB6F from STMicroelectronics, in a SOT-23-6. 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 | RST | tri_state | Active-low open-drain reset output driven low when VCC1, VCC2, or RSTIN falls below factory-trimmed threshold or MR is asserted; held low for minimum delay trec after all supplies recover and MR returns high; requires external pull-up resistor to VCC1 (10 kΩ typical). |
| 2 | VSS | power_in | Ground reference. |
| 3 | MR | input | Active-low push-button reset input with internal 50 kΩ pull-up to VCC1; asserts RST output low when driven low; remains low for minimum delay trec after returning high. |
| 4 | VCC2 | power_in | Secondary supply voltage monitoring input with factory-programmed reset threshold VRST2 (1.665 V typical for STM6719TW); available threshold range 3.08 V to 0.79 V. |
| 5 | RSTIN | input | High-impedance adjustable reset comparator input; drives RST output low when voltage falls below 0.626 V internal reference; external resistor-divider network sets monitored threshold. |
| 6 | VCC1 | power_in | Primary supply voltage monitoring input with factory-programmed reset threshold VRST1 (3.075 V typical for STM6719TW); available threshold range 4.63 V to 1.58 V; serves as reference for RST output high voltage and MR internal pull-up. |
