STM6777SYWB6F 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 | output | Active-low reset output that is open drain on the STM6777 and must be pulled up to VCC1 (10 kΩ is sufficient for most applications); it is driven low whenever VCC1, VCC2 or MR goes low and stays low for trec after all monitored supplies are above threshold and MR returns high. |
| 2 | VSS | power_in | Ground reference for the supervisor. |
| 3 | MR | input | Active-low push-button manual reset input with an internal 50 kΩ pull-up (25 kΩ to 80 kΩ) to VCC1; it can be driven from TTL/CMOS or open-drain logic or switched to VSS, and may be left open or tied to VCC1 if unused. |
| 4 | VCC2 | power_in | Secondary supply voltage monitoring input with factory-programmed reset thresholds from 3.08 V to 0.79 V (operating range 0.8 V to 3.6 V for VCC2 in the DC tables). |
| 5 | MRC | input | Manual reset delay input that is left open for the minimum delay (6 µs or more) or connected to VSS through a capacitor to lengthen the manual reset delay (about 4 s typical with 3.3 µF). |
| 6 | VCC1 | power_in | Primary supply voltage input and reset threshold monitor with factory-programmed thresholds from 4.63 V to 1.58 V, operating over 0.8 V to 5.5 V. |
