The document describes the features and characteristics of the TPS3307 series of triple processor supervisors. The product is designed for DSP and processor-based systems that require multiple supply voltages. It features a power-on reset generator with a fixed delay time of 200ms, eliminating the need for an external capacitor. The product also includes a temperature-compensated voltage reference and has a maximum supply current of 40µA. It is suitable for applications such as industrial equipment, programmable controls, automotive systems, portable/battery-powered equipment, intelligent instruments, wireless communication systems, and notebook/desktop computers.
The TPS3307 series provides triple supervisory circuits for DSP, microcontroller and microprocessor based systems. Each device monitors three supply voltages (SENSE1‑3) and generates active‑low and active‑high RESET outputs, with an optional manual reset input.
The devices are offered in MSOP‑8 and SO‑8 packages, operate from –40 °C to +85 °C, and feature a fixed 200 ms power‑on reset delay without external components. Typical applications include industrial equipment, portable battery‑powered devices, automotive systems and wireless communications.
