PST893B

MITSUMI System Reset IC with delay PST89XB Series 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. Features 1. Maximum supply voltage 2. Detecting voltage accuracy 3. Low supply current 4. Operating supply voltage 5. Operating temperature 6. Reset voltage rank 7. Reset temperature coefficient 8.
