System Reset IC with delay

Monolithic IC PST89XB Series

Outline

This IC is a reset IC for turning on/off power supply and power ﬂicker in CPU or logic systems.

This IC can change delay time by an external capacitor.

Charging method of the capacitor, is current source type.

Current source type can reduce temperature ﬂuctuations in the delay time. td typ. 6% (Ta= 40°C to 105°C), It is ideal

for a wide set the operating temperature range.
