STM1818TWX7F Description

Short technical summary and product information.

The STMicroelectronics STM1818TWX7F is a voltage supervisory circuit designed to monitor system power supply integrity. It operates with a supply voltage ranging from 1.2V to 5.5V and consumes a typical operating current of 16 uA. The device features an active low, open drain output, indicating a reset condition when the voltage drops below a specified threshold.

This supervisory circuit includes manual reset capability and monitors a single input. It does not feature a watchdog timer or battery backup switching. The STM1818TWX7F is housed in a compact SOT-23-3 surface-mount package, making it suitable for space-constrained applications. It is rated for a maximum power dissipation of 320 mW and operates across a wide temperature range of -40°C to +105°C.

Key electrical specifications include threshold voltages of 3V, 3.3V, and 5V, with specific overvoltage and undervoltage thresholds of 3.15V and 2.98V, respectively. The absence of chip enable signals and power fail detection simplifies its integration into various designs. The standard package quantity is 3000 units on a reel.

This component is ideal for applications requiring reliable power supply monitoring and reset generation. Its robust operating temperature range and small footprint facilitate its use in diverse electronic systems.
