STMICROELECTRONICS STM809LWX6F Reset Circuit

The STM809 series are low-power supervisory reset devices designed to monitor power supply voltages of 3 V, 3.3 V, and 5 V, ensuring microcontroller stability. They feature push-pull reset outputs, a reset pulse width of at least 140 ms, and operate from -40°C to 85°C in lead-free SOT23 and SOT143 packages. These reset circuits provide guaranteed assertion down to 1.0 V, are immune to negative Vcc transients, and include manual reset inputs for manual control in noisy environments, offering reliable system power management.
