Description
RNA51953A,B are semiconductor integrated circuits designed for detecting supply voltage and resetting all types
of logic circuits such as CPUs.
They include a built-in delay circuit to provide the desired retardation time simply by adding an external capacitor.
They fined extensive applications, including battery checking circuit, level detecting circuit and waveform shaping
circuit.
Features
• Few external parts
• Large delay time with a capacitor of small capacitance (td ≈ 100 ms, at 0.33 µF)
• Low threshold operating voltage (Supply voltage to keep low-state at low supply voltage):
0.6 V (Typ) at R_L = 22 kΩ
• Wide supply voltage range: 2 V to 17 V
• Wide application range
• Ordering Information
