V6309 - 3-Pin Microprocessor Reset Circuit

General Description

The V6309 and V6319 are microprocessor supervisory circuits 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 5 V powered or 3 V powered circuits.

Key Features

  • n Precision monitoring of 3 V, 3.3 V and 5 V power supply voltages n Fully specified over the temperature range of -40 to + 125 oC n 140 ms minimum power-on reset pulse width: RESET output for V6309 RESET output for V6319 n 16 µA supply current n Garanteed RESET/RESET valid to VDD = 1 V n Power supply transient immunity n No external components needed n 3-pin SOT-23 package n Fully compatible with MAX809/MAX810 and AMD809/AMD810 Typical Operating Configuration.
