STM806SM6F

STMicroelectronics · Supervisor And Reset ICs · SOIC-8

STM806SM6F from STMicroelectronics, 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 VOUT power_out When VCC is above the switchover voltage (VSO), VOUT is connected to VCC through a P-channel MOSFET switch, and when VCC falls below VSO, VBAT connects to VOUT; connect to VCC if no battery is used.
2 VCC power_in Supply voltage input; reset is guaranteed valid down to VCC = 1 V without a backup battery.
3 VSS power_in Ground reference for the device.
4 PFI input When PFI is less than VPFI or VCC falls below VSW (2.4 V), PFO goes low; connect to ground if unused.
5 PFO output Push-pull power-fail output that goes low when PFI is less than VPFI or VCC falls below VSW, and is left open if unused.
6 MR input Active-low push-button reset input with an internal 40 kΩ pull-up that asserts reset while low and for trec after it returns high; leave open if unused.
7 RST output Active-low reset output that stays low whenever VCC is below the reset threshold or MR is low, and for trec after either condition clears.
8 VBAT power_in Backup battery input; when VCC falls below VSO, VOUT switches from VCC to VBAT, and VBAT may exceed VCC; connect to VCC if no battery is used.
