STM6779SWB6F

STMicroelectronics · Supervisor And Reset ICs · SOT-23-6

STM6779SWB6F 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 open-drain reset output; driven low when VCC1 or RSTIN falls below its threshold or when MR is asserted; remains low for trec after all monitored supplies recover above thresholds and MR returns high.
2 VSS power_in Ground; negative supply reference.
3 MR input Active-low push-button reset input with internal 50 kΩ pull-up resistor to VCC1; driving low asserts RST and maintains it low for trec after release.
4 MRC input Manual reset delay input; leave open for 6 µs minimum delay or connect capacitor to VSS to implement delays from microseconds to seconds depending on capacitor value.
5 RSTIN input Adjustable reset comparator input (high impedance); monitors external threshold set via resistor divider network; asserts RST when voltage falls below 0.626 V internal reference.
6 VCC1 power_in Primary supply voltage monitoring input; reset threshold factory-programmed based on device suffix (4.63 V to 1.58 V range); also provides reference for push-pull RST outputs on other variants.
