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.
