Формирователи импульса сброса MAX6383XR31D3+T

Схема контроля , активный низкий, открытый сток, 1В - 5.5В, 3.08В порог, 140мс задержка, SC-70-3

The MAX6383XR31D3+T from Maxim Integrated Products is a single, low voltage, low power microprocessor (µP) reset circuit in 3 pin SC70 package. This µP supervisory circuits monitor power supply voltages from +1.8V to +5.0V 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 is ideally used at computers, controllers, intelligent instruments, critical µP and µC power monitoring and portable/battery powered equipment.

• Operating voltage range from 1V to 5.5V
• Operating temperature range from -40°C to +125°C
• Open drain active-low reset output
• ±2.5% reset threshold accuracy over temperature (-40°C to +125°C)
• Reset output state guaranteed valid down to VCC = 1V
• 3.08V reset threshold
• 140ms minimum and 280ms maximum reset timeout delay
• Negative going VCC transient immunity
• Low power consumption of 6µA at +3.6V and 3µA at +1.8V
