Формирователи импульса сброса MAX6386LT29D3+T

Схема контроля микропроцессора , 1В-5.5В питание, выход сброса с активным низким, с открытым стоком

The MAX6386LT29D3+T is a single low voltage, low power microprocessor (µP) reset circuit in 6 pin UDFN package. This microprocessor (µP) supervisory circuit monitors power supply voltage ranging from +1.8V to +5V while consuming only 3µA of supply current at +1.8V. Whenever VCC falls below the factory-set reset thresholds, the reset output asserts and remains asserted for a minimum reset timeout period after VCC rises above the reset threshold. It has an open-drain active-low reset output and debounced manual reset input. Typical application includes controllers, intelligent instruments, critical microprocessor (µP) and microcontroller (µC) power monitoring and battery powered equipment.

• Supply voltage range is 1V to 5.5V
• Operating temperature range from -40°C to 125°C
• Reset threshold voltage is 2.93V
• Reset threshold accuracy is ±2.5%
• Reset timeout delay is 280ms
• Reset output state is valid to VCC = 1V
• Negative going VCC transient immunity
• Low power consumption of 6µA at +3.6V
