PT7M3808中文资料Low Quiescent Programmable-Delay Supervisory数据手册Diodes规格书

描述 Description

The PT7M3808G family of microprocessor supervisory circuits monitor system voltage form 0.4V to 5.0V, asserting an open-drainRESET signal when the SENSE voltage drops below a preset threshold or when the manual reset (MR ) pin drops to a logic low. The RESET output remains low for the user-adjustable delay time after the SENSE voltage and manual reset (MR ) return above the respective thresholds.

特性 Features

•Power-On Reset Generator with Adjustable Delay Time: 1.25ms to 10s.
•Very Low Quiescent Current: 2.8µA Typical
•High Threshold Accuracy: 0.5% Typ.
•Fixed Threshold Voltages for Standard Voltage Rails from 0.9V to 5V A18and Adjustable Voltage Down to 0.4V are available.
•Manual Reset (MR ) Input.
•Open-Drain RESET Output. 
•Temperature Range: -40°C to +125°C 
•Package: TDFN2.0x2.0-6L and SOT23-6L

应用 Application

•DSP or Microcontroller Applications capacitor.
•Notebook/Desktop Computers
•Hand-Held Products battery-powered applications.
•Portable/Battery-Powered Products
•FPGA/ASIC Applications
