This polarity matches processors that expect a high-true reset input. ## Package and temperature grade Only one voltage is monitored, so this is a straightforward power-good watchdog for a single rail — not a sequencer or multi-voltage supervisor. The threshold is fixed at 2.93V, typical for 3.3V logic rails where a brownout below ~2.9V signals an unreliable supply.","metaTitle":"STM812SW16F Simple Reset/Power-On Reset, 2.93V Threshold","metaDescription":"STMicroelectronics STM812SW16F supervisor IC, Active High reset, 140ms timeout, -40°C to 85°C, SOT-143-4.
