TS809/810/809R/810R series microprocessor reset circuit is a microprocessor (µP) supervisory circuit used to monitor the power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V powered circuits.
The TS809/810 series are microprocessor supervisory circuits that monitor power supplies in UP and digital systems. They generate a reset signal when VCC falls below a preset threshold and keep it asserted for at least 140 ms after VCC rises above the threshold. The series offers both active‑low (TS809/809R) and active‑high (TS810/810R) push‑pull reset outputs and operates down to 1 V.
