STM6719SFBWB6R

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

STM6719SFBWB6R 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, VCC2, or RSTIN falls below factory-programmed reset threshold or when MR goes to logic low; remains low for minimum trec of 8.8 ms after all supply voltages return above threshold and MR returns to high (B variant).
2 VSS power_in Ground; negative supply reference for all monitoring comparators and logic circuits.
3 MR input Push-button manual reset input (active-low) with internal 50 kΩ pull-up resistor to VCC1; input voltage range 0.3·VCC1 to 0.7·VCC1; minimum pulse width 1 µs; if unused, leave open or connect to VCC1.
4 VCC2 power_in Secondary supply voltage monitoring input; fixed factory-programmed reset threshold VRST2 of 1.050 V (SF variant); operating voltage range 0.8 V to 3.6 V; 0.1 µF bypass capacitor recommended.
5 RSTIN input Adjustable reset comparator input (high impedance); RST driven low when RSTIN falls below 0.626 V ±16 mV internal reference threshold; external resistor-divider network sets the monitored voltage threshold.
6 VCC1 power_in Primary supply voltage monitoring input; fixed factory-programmed reset threshold VRST1 of 2.925 V (SF variant); operating range 0.8 V to 5.5 V; primary power supply for device operation; 0.1 µF bypass capacitor recommended.
