Description
RNA51958A,B are semiconductor integrated circuits for resetting of all types of logic circuits such as CPUs, and has
the feature of setting the detection voltage by adding external resistance.
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 F)
 Wide supply voltage range: 2 V to 17 V
 Wide application range
 Ordering Information
