STM1816RWX7F ST Supervisors

The STM1816RWX7F is a low-power microprocessor supervisory circuit from STMicroelectronics in SOT-23-3 surface-mount package, monitoring 2.63V supply threshold with active-high push-pull reset output, manual reset input, and watchdog timer with 100ms timeout. For selection, verify reset threshold of 2.63V with ±2% accuracy suitable for low-voltage 2.5V/2.7V system monitoring, supply from 1V to 5.5V, reset timeout period of 100ms typical, low supply current of 16µA typical, and operating temperature from -40°C to +85°C. Features include active-high push-pull reset output (no external pull-up required), manual reset input for external override, guaranteed reset valid down to 1V VCC for reliable power-on reset, and excellent transient immunity. Ideal for low-voltage microprocessor systems (2.5V/2.7V), industrial controllers, portable equipment, automotive electronics, and embedded systems requiring power-on reset, brown-out protection, and manual reset capability with active-high reset polarity.
