The Renesas RNA51957A is a semiconductor integrated circuit designed for resetting logic circuits such as CPUs. It features a wide supply voltage range from 2 V to 17 V and a low threshold operating voltage of 0.6 V (Typ) at RL = 22 kΩ.
This IC includes a built-in delay circuit, allowing for desired retardation time by adding an external capacitor. A capacitor of 0.33 µF can provide a delay time of approximately 100 ms. The RNA51957A is suitable for various applications including battery checking circuits, level detecting circuits, and waveform shaping circuits.
Available in SOP-8 and DIP-8 packages, the RNA51957A is designed for surface mounting. The device has an output sink current of 6 mA and power dissipation ratings of 570 mW for the SOP-8 package and 4.4 mW for the DIP-8 package.
