RNA51953A,B
Voltage Detecting, System Resetting IC Series
REJ03D0911-0100 Rev.1.00 Oct 10, 2008
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.
