Формирователи импульса сброса MAX6701ATKA+T

Схема контроля , ручной, двухтактный, 3 монитора, 1.2В - 5.5В, 200мс задержка, SOT-23-8

The MAX6701ATKA+T from Maxim Integrated Products is a low voltage, µP supervisor with power-fail in/out, manual reset and watchdog timer in 8 pin SOT-23 package. It reduces the complexity and components required to monitor power supply functions in µP systems and significantly improve system reliability and accuracy compared to separate ICs or discrete components. It provides four functions such as, a reset output during power-up, power-down and brownout conditions, an independent watchdog output that goes low if the watchdog input has not been toggled within 1.6s, a 0.62V threshold detector for power-fail warning and an active-low manual reset input. It offers several pin-out options to accommodate a variety of multivoltage microprocessor supervision applications. It is used in computers, controllers, intelligent instruments, critical µP power monitoring, white goods, networking and telecommunications applications.

• Operating voltage range is 1.2V to 5.5V at TA = -40°C to +125°C
• Active-low WDO deasserts when active-low MR is pulled low
• Active low push-pull reset output, 60ppm
• °C reset threshold temperature coefficient
• Precision monitoring of +5V, +3.3V, +3V and +2.5V supply voltages
• Reset valid to VCC = 1V, immune to short falling VCC transients
• Monitors 3 supply voltages (one fixed threshold and two adjustable) to drive a single reset output
• Low cost, few external components, operating temperature range from -40°C to 125°C
• VCC reset threshold (VCC falling) of 3.08V at TA = -40°C to +85°C
• Reset timeout period of 200ms at TA = -40°C to +85°C

• Dual adjustable reset input for triple voltage monitoring
