STMicroelectronics Voltage Supervisor 1 Supervisor 3-Pin SOT-23 3.15 V STM1816TWX7F

The STMicroelectronics STM1816TWX7F is a single voltage supervisor packaged in a 3-pin SOT-23 form factor designed to monitor and supervise the supply voltage ensuring reliable operation of microprocessor and microcontroller systems.

Its reset threshold voltage of 3.15 V precisely detects voltage dips below this level, triggering a reset signal through its open drain, active low output driver. This ensures that integrated circuits receive a stable power supply, preventing malfunction during brownouts or power interruptions.

Featuring a compact surface-mount SOT-23 package with dimensions 3.04 mm length, 1.4 mm width, and 1.02 mm height, it is suited for space-constrained industrial, commercial, and consumer electronics applications.

Designed for a broad supply voltage range, it operates from a minimum 1.2 V up to a maximum of 5.5 V, making it compatible with a wide variety of power sources. The supervisor is rated for operation within -40°C to 105°C ambient temperature, supporting automotive and industrial temperature environments (though not specifically automotive certified).

Its single supervisor monitors a nominal voltage of 3.06 V to maintain proper logic state and system reset. Manual reset and watchdog timer features are not present, simplifying integration where these are not required.

Ensures stable microprocessor operation by monitoring supply voltage. Minimal footprint with 3-pin SOT-23 surface-mount package. Triggers reset with open-drain, active low output signaling. Wide operating voltage from 1.2 V to 5.5 V.

Automotive standard compliance is not present but industrial and commercial use supported. Temperature rating from -40°C to +105°C ensures robust performance. Ideal for power supply monitoring in desktops, laptops, portable equipment, and multi-output power supplies.

Set contains a single STMicroelectronics STM1816TWX7F Voltage Supervisor in SOT-23 package, ready for surface mounting on PCB for system voltage monitoring and reset applications.
