Dual-rail supervisor for 3.3V and 5V systems
The TPS3305-33DGNR from Texas Instruments monitors two independent supply voltages with thresholds at 2.93V and 4.55V, making it a direct fit for systems that need supervision on both a 3.3V and a 5.0V rail. It provides both an active-high and an active-low reset output from a single push-pull stage, so you can drive reset inputs on mixed-logic devices without external inversion.
The part is housed in an 8-HVSSOP package (3.00mm width, exposed pad) and is rated for operation from -40°C to 85°C junction temperature, covering most industrial and outdoor telecom environments. The TPS3305-33DGNR is ROHS3 compliant, which simplifies compliance for EU and other regulated markets.
