TS809R - Microprocessor Reset Circuit

Download the TS809R datasheet PDF. This datasheet also covers the TS809 variant, as both devices belong to the same microprocessor reset circuit family and are provided as variant models within a single manufacturer datasheet.

General Description

The TS809/810 series are microprocessor (µP) supervisory circuit used to monitor the power supplies in µP and digital systems.

They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V powered circuits.

Key Features

  • Highly Accurate: ±2%.
  • Precision monitoring of +3V, +3.3V and +5V power supply voltage.
  • Fully specified over temperature.
  • Available in three output configurations.
  • Push-Pull RESET low output (TS809/TS809R).
  • Push-Pull (RESET) high output (TS810/TS810R).
  • 140mS min. power-on reset pulse width.
  • 12uA supply current.
  • Guaranteed reset valid to Vcc = +1V.
  • Power supply transient immunity.
  • No external components.

TS809/810/809R/810R Series Microprocessor Reset Circuit SOT-23 Pin Definition: TS809/TS810 1. Ground 2. RESET(RESET) 3. Vcc TS809R/TS810R 1. RESET(RESET) 2. Ground 3. Vcc General Description The TS809/810 series are microprocessor (µP) supervisory circuit used to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V powered circuits. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available.
