Texas Instruments TPS3307-18M Triple Processor Supervisors TPS3307-18MJGB

The TPS3307-18MJGB is a triple processor supervisor designed for monitoring multiple supply voltages in DSP and processor-based systems, particularly in military and industrial applications. 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 TPS3307-18MJGB 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 supply voltage exceeds 1.1 V and maintains this state until all monitored voltages rise above their respective thresholds. The device also incorporates a manual reset input, allowing for additional control over the RESET output. Qualified for military applications, the TPS3307-18MJGB offers ESD protection exceeding 2000 V per MIL-STD-883 and operates over a wide temperature range of -55¬8C to 125¬8C. It is available in both CDIP-8 and LCCC-20 packages, making it suitable for various design requirements.
