Description

RNA51957A,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.

Key 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 RL = 22 kΩ
  • Wide supply voltage range: 2 V to 17 V
  • Wide application range
