TPS3307 is a triple processor supervisor from Texas Instruments, designed for circuit initialization primarily in DSP and processor-based systems, which require more than one supply voltage. It can monitor three independent power voltages, and has a power-on reset generator and temperature-compensated voltage reference functions.
The TPS3307‑18, TPS3307‑25 and TPS3307‑33 are micropower supply voltage supervisors designed for DSP and processor‑based systems that require monitoring of three independent supply voltages. They feature a fixed 200 ms power‑on reset delay, a manual reset input (MR), and both active‑low and active‑high reset outputs.
The devices are offered in 8‑pin MSOP or SO packages, operate over a temperature range of –40 °C to 85 °C, and support supply voltages from 2 V to 6 V. Typical applications include automotive systems, portable equipment, intelligent instruments, and notebook or desktop computers.
| Supply Voltage Range | 2 V to 6 V |
|---|---|
| Maximum Supply Current | 40 µA |
| Operating Temperature Range | –40 °C to 85 °C |
| Package Types | MSOP‑8 and SO‑8 |
| Reset Delay Time | 200 ms |
The internal timer provides a 200 ms delay before the RESET output returns to the inactive state.
The TPS3307 operates with a supply voltage (Vpp) between 2 V and 6 V.
The device provides three sense inputs: SENSE1, SENSE2 and SENSE3.
They are offered in 8‑pin MSOP and standard 8‑pin SO packages.
