DIO6809L中文资料Ultra Low Power Microprocessor Reset Circuit数据手册DIOO规格书

描述 Description

DIO6809 series are micro-processor(μP) 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.

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.

The DIO6809 has CMOS outputs. The DIO6809 has an active-low /RESET output, Thereset comparator is designed to ignore fast transients on VCC, and the outputs are guaranteed to be in the correct logic state for VCC down to 1.0V over the temperature range.

The device is available in 3 pin SOT-23 and SOT-23-3L package.
