Ultra-Low-Power Voltage Supervisor (Reset IC) – Single-channel voltage supervisor designed for microcontrollers, processors, IoT devices, industrial control systems, automotive electronics, battery-powered equipment, and embedded systems requiring reliable power-on reset and brownout detection. The Texas Instruments TLV803EA30DBZR monitors a 3.0 V supply rail with a 3.08 V reset threshold, providing an active-low open-drain RESET output to ensure proper system initialization and recovery during undervoltage conditions. Features 250 nA typical quiescent current, 130 ms minimum reset timeout, supply voltage operation from 0.7 V to 6 V, and open-drain output for easy interfacing with multiple voltage domains. Includes power-on reset, brownout protection, and low-power operation, making it ideal for energy-efficient embedded applications. Operates over a −40°C to +125°C temperature range and is housed in a compact 3-pin SOT-23 (DBZ) package for surface-mount designs.
