Key Features
- Fixed 4.38 V supervisory threshold with precision internal reference for accurate 5 V rail undervoltage detection
- Active-low manual reset input allows external push-button or logic signal to assert system reset independently of supply voltage
- 8-pin SOIC surface-mount package minimizes board area while providing standard reset output and watchdog-compatible pinout
Applications
STM706M6F is used to supervise the 5 V power rail in microprocessor and microcontroller systems, asserting a reset signal whenever the supply drops below 4.38 V to prevent data corruption during brownout or power-down events. The manual reset input allows front-panel push-buttons or system management controllers to force a CPU reset without cycling power. It is well suited for industrial PLCs, embedded computing boards, and communication equipment where reliable 5 V rail supervision is needed in an 8-pin SOIC footprint.

Frequently Asked Questions
At what supply voltage does STM706M6F assert its reset output, and how precise is the threshold?
STM706M6F asserts its active-low RESET output when the monitored supply falls below the fixed 4.38 V threshold. The internal precision reference keeps the trip point within ±2% of 4.38 V across the -40°C to +85°C operating range, so the actual assert voltage is guaranteed between approximately 4.30 V and 4.46 V. This accuracy ensures the microprocessor is held in reset before the 5 V rail drops to levels that would corrupt SRAM or flash write operations.
How does the manual reset input of STM706M6F work in a front-panel push-button reset circuit?
The MR pin on STM706M6F is an active-low input that asserts the RESET output when pulled low, independent of the supply voltage level. A normally-open push-button connected between MR and GND with a 10 kΩ pull-up resistor to VCC allows an operator to force a CPU reset by pressing the button. The minimum pulse width required is typically 140 µs, after which RESET remains asserted for the full reset timeout period of approximately 200 ms before deasserting.
How does STM706M6F compare to a simple RC power-on reset circuit for 5 V microprocessor supervision?
An RC reset circuit using a 10 kΩ resistor and 10 µF capacitor provides only a one-time power-on delay of approximately 100 ms and cannot detect brownout events where VCC sags below 4.38 V during operation. STM706M6F continuously monitors the rail and re-asserts reset whenever undervoltage is detected, which a passive RC network cannot do. The 8-pin SOIC IC also adds the manual reset input and a guaranteed reset pulse width of about 200 ms, making it far more reliable in industrial environments where mains fluctuations are common.
