SM72240中文资料5 引脚微处理器复位电路数据手册TI规格书
SM72240规格书详情
描述 Description
The SM72240 microprocessor supervisory circuit monitors the power supplies in microprocessor and digital systems. It provides a reset to the microprocessor during power-up, power-down, brown-out conditions, and manual reset.
The SM72240 asserts a reset signal whenever the supply decreases below the factory-programmed reset threshold. Reset will be asserted for at least 100ms even after VCC rises above the reset threshold.
The SM72240 has an active-low open-drain RESET output.
The SM72240 is suitable for monitoring 5V. With a low supply current of only 6µA, the SM72240 is ideal for use in portable equipment. The SM72240 is available in the 5-pin SOT-23 package.
特性 Features
• Renewable Energy Grade
• Fully specified over temperature
• 100 ms minimum Power-On Reset pulse width, 190 ms typical:
• RESET Output valid for VCC ≥ 1V
• Power supply transient immunity
• Compatible with MAX811/812 applications
