STM811MW16F ST Supervisors

The STM811MW16F is a low-power microprocessor supervisory circuit from STMicroelectronics in SOT-143-4 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, 140ms minimum reset timeout, low supply current of 5-10µA, and operating temperature from -40°C to +105°C. Features include manual reset input with internal debounce circuit, push-pull reset output eliminating external pull-up resistor, guaranteed reset valid down to 1V VCC, and excellent transient immunity. Ideal for 5V microprocessor and microcontroller systems, industrial controllers, portable equipment, automotive electronics, and embedded systems requiring power-on reset and brown-out protection with manual reset.
