STM1813MWX7F ST Supervisors

The STM1813MWX7F is a low-power microprocessor supervisory circuit from STMicroelectronics in SOT-23-3 package, monitoring 4.38V supply threshold with active-low push-pull reset output. For selection, verify supply from 1V to 5.5V, reset threshold of 4.38V with ±2% accuracy (suitable for 5V system monitoring), 100 ms minimum reset timeout, low supply current of 16 µA typical, and operating temperature from -40°C to +85°C. Features include push-pull reset output eliminating external pull-up resistor, manual reset input for external override, guaranteed reset valid down to 1V VCC for reliable power-on reset, and excellent transient immunity. Ideal for 5V microprocessor systems, industrial controllers, portable equipment, automotive electronics, and embedded systems requiring power-on reset, brown-out protection, and manual reset capability for 5V supply rails.
