Формирователи импульса сброса MAX6320PUK46CY+T

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

The MAX6320PUK46CY+T is a µP supervisory circuit with watchdog and manual reset in 5 pin SOT-23 package. This microprocessor (µP) supervisory circuit monitors power supplies and microprocessor activity in digital systems. It reset input starts or restarts the µP in a known state. The reset output of µP supervisory circuit interfaces with reset input of the µP, preventing code-execution errors during power-up, power-down and brownout conditions. It is used in embedded control systems and intelligent instruments.

• Supply voltage range is 1V to 5.5V
• Operating temperature range from -40°C to 125°C
• Minimum reset timeout is 140ms & typical watchdog timeout is 1.6s
• Factory-trimmed reset thresholds is 4.63V at TA = +25°C
• Manual reset input
• Active-low open drain reset output
• Integrated configuration enables flexible designs
• Integrated features increase robustness, reset valid to VCC = 1V
• Immune to short-negative VCC transients
• Saves board space, no external components required
