The TPS3307 family is a series of micropower supply voltage supervisors designed for circuit initialization primarily in DSP and processor-based systems, which require more than one supply voltage.
The TPS3307 family provides three independent supply‑voltage supervisors for DSP, microcontroller, and microprocessor‑based systems. Typical applications include automotive systems, portable battery‑powered equipment, intelligent instruments, and wireless communication devices. The devices monitor up to three supply rails (e.g., 3.3 V/1.8 V/adjustable) and generate a RESET signal when any monitored voltage falls below its threshold.
Key features include a fixed 200 ms power‑on reset delay, a manual reset input (MR), both active‑low and active‑high RESET outputs, a temperature‑compensated reference, and low quiescent current (40 µA). The parts are offered in 8‑pin MSOP and SO packages and operate from 2 V to 6 V across –40 °C to 85 °C.
