Формирователи импульса сброса MAX6321HPUK46CY+T

Схема контроля , двухтактный, открытый сток, 1-5.5В, 4.63В порог, 200мс задержка, SOT-23-5

The MAX6321HPUK46CY+T from Maxim Integrated Products is an automotive grade microprocessor (µP) supervisory circuit with watchdog and manual reset in 5 pin SOT23 package. This µP monitors power supplies and microprocessor activity in digital systems. It offers several combinations of push/pull, open-drain and bidirectional (such as Motorola 68HC11) reset outputs, along with watchdog and manual reset features. It is ideally used at portable computers, controllers, computers, intelligent instruments, portable/battery-powered equipment and embedded control systems.

• Supply voltage range is 1V to 5.5V
• Operating temperature range from -40°C to +125°C
• Reset output stages active high push
• pull and active low open-drain
• Watchdog input, integrated features increase robustness
• Guaranteed reset valid to VCC = 1V, immune to short-negative VCC transients
• 4.63V reset threshold
• 140ms minimum reset time
• 1.6s typical watchdog time out
• Saves board space, no external components

• Computers; Controllers; Embedded Control Systems; Intelligent Instruments; Portable Battery-Powered Equipment; Portable Computers
