Description
This IC facilitates complicated power-on and power-monitoring resets of microcomputers that require the 3.3-V and
1.8-V dual power supplies. It also facilitates change of delay time of reset signal by externally setting resistance and
capacity for delay time. By employing complementary open-drain output, desired output such as open-drain output and
CMOS output can be obtained.
Functions
• 3.3-V detection voltage
• Accuracy of 3.3-V detection voltage
• Hysteresis of 3.3-V detection voltage
• Open-drain/CMOS output
• 1.8-V PMOS drive output
• Ultra-small SSOP-8 package
: 2.7 V
: ±1.0%
: 5% Typ.
