Формирователи импульса сброса MAX6861UK29+T

Схема контроля , Nanopower, ручная, активный низкий двухтактный, 1.2В до 5.5В, порог 2.925В, SOT-23-5

The MAX6861UK29+T from Maxim Integrated Products is a nanopower microprocessor (µP) supervisory circuit with manual reset input in 5 pin SOT-23 package. This microprocessor (µP) supervisory circuit combines voltage monitoring and manual reset input functions. The device asserts a reset signal whenever the monitored voltage drops below factory trimmed reset threshold voltage or manual reset is asserted. The reset output remains asserted for a minimum timeout period after VCC rises above the reset threshold and manual reset is deasserted. Typical applications include portable/battery powered equipment, PDAs/cell phones, MP3 players/pagers, glucose monitors/patient monitors.
