The TPS3307-18QDRQ1 is a micropower supply voltage supervisor designed for automotive applications, particularly for monitoring multiple supply voltages in DSP and processor-based systems. It features three independent supervisory circuits capable of monitoring voltages of 3.3 V, 1.8 V, and an adjustable user-defined voltage above 1.25 V. The device operates within a supply voltage range of 2 V to 6 V and has a maximum supply current of 40 µA. The TPS3307-18 includes a power-on reset generator with a fixed delay time of 200 ms, eliminating the need for an external capacitor. It asserts a RESET output when the monitored supply voltages fall below their respective thresholds, ensuring proper system initialization. The device also incorporates a manual reset input, allowing for additional control over the RESET state. It is housed in an 8-pin SO package and is rated for operation over a temperature range of -40°C to 125°C, making it suitable for harsh automotive environments.
