What are the key features of STM6825RWY6F?
- Integrated overvoltage detection and undervoltage supervisor in one 5-pin SOT-23 IC, replacing two discrete comparators with a single factory-trimmed device
- Active-low manual reset input allows pushbutton or external logic to force MCU reset independently of supply voltage level, simplifying system reset architecture
- Monitors supply rails from 1.7 V to 5.5 V with factory-preset thresholds and a defined reset timeout pulse, ensuring reliable processor startup without external RC timing networks
What is STM6825RWY6F used for?
STM6825RWY6F is used in microcontroller-based industrial controllers, consumer appliances, and IoT edge devices where reliable power-on reset, brownout recovery, and overvoltage protection are required without external discrete components. Its manual reset input and compact 5-pin SOT-23 package make it a drop-in supervisor solution for 3.3 V or 5 V MCU reset lines, reducing BOM complexity and ensuring deterministic reset behavior across the full -40 °C to +85 °C operating temperature range.

Frequently Asked Questions
What supply voltage range does STM6825RWY6F supervise, and what temperature range does it cover?
STM6825RWY6F monitors supply voltages from 1.7 V to 5.5 V, covering 1.8 V, 2.5 V, 3.3 V, and 5 V rail targets with a single device family. It operates across -40 °C to +85 °C, making it suitable for industrial control panels, outdoor IoT nodes, and automotive accessory boards that experience wide ambient temperature swings during normal service.
How does STM6825RWY6F overvoltage detection protect an MCU-based design compared to using only a brownout supervisor?
A brownout-only supervisor triggers reset when supply drops below threshold but ignores overvoltage events caused by regulator failures or load-dump transients. STM6825RWY6F adds overvoltage detection above the nominal rail, asserting the active-low reset output when supply exceeds the upper limit, preventing MCU data corruption or latch-up at voltages beyond the device absolute maximum. This dual-direction monitoring in a single 5-pin SOT-23 IC eliminates the need for a separate overvoltage comparator and associated 2-4 passive components.
When is STM6825RWY6F a better choice than a simple RC reset network for 3.3 V MCU power sequencing?
An RC reset network provides only a fixed time delay and has no supply-voltage monitoring, meaning it cannot distinguish between a clean power-up and a brownout event at 3.3 V. STM6825RWY6F uses factory-trimmed threshold voltages and a defined reset timeout pulse length, guaranteeing that the MCU reset line stays asserted until the 3.3 V rail is stable, regardless of supply ramp rate. It also provides a manual reset input for pushbutton functionality, replacing 3 to 5 passive components with a single calibrated IC in the 5-pin SOT-23 footprint.
