Формирователи импульса сброса MAX6764UT+T

Схема контроля микропроцессора , 1В-6В питание, выход сброса с активным низким, с открытым стоком

The MAX6764UT+T is a low power, single voltage window detector in 6 pin SOT-23 package. This window detector monitor undervoltage/overvoltage conditions on system power supplies and assert when the monitored voltage is under the undervoltage and/or over the overvoltage thresholds. It is a single voltage window detector with internally fixed nominal voltage, externally adjustable set window, single reset undervoltage/overvoltage output and a manual reset input. Whenever a monitored voltage falls below its undervoltage threshold or exceeds its overvoltage threshold, device asserts its output to notify the system. It is used in telecommunication, data storage, power metering, DC-DC converter and modules.

• Supply voltage range is 1.4V to 6V
• Operating temperature range from -40°C to 125°C
• Active-low, open drain reset type
• Selectable window threshold options (±5%, ±10%, ±15%)
• Timeout period options of 20µs (typ) propagation delay or 100ms (min) reset timeout
• Externally adjustable window monitoring options for supplies down to 0.5V
• Single (Combined UV
• OV) or Dual (Separate UV and OV) Outputs
• Immune to short voltage transients, low supply current of 10µA
• Low-voltage operation (outputs valid for VCC down to 1V)
