1 / 10 page REJ03D0911-0100 Rev.1.00 Oct 10, 2008 Page 1 of 9 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): 0.6 V (Typ) at RL = 22 kΩ • Wide supply voltage range: 2 V to 17 V • Wide application range • Ordering Information Part Name Package Type Package Code Package Abbreviation Taping Abbreviation (Quantity) Surface Treatment RNA51953AFPH0 SOP-8 pin PRSP0008DE-C FP H (2,500 pcs / Reel) 0 (Ni/Pd/Au) RNA51953BFPH0 SOP-8 pin PRSP0008DE-C FP H (2,500 pcs / Reel) 0 (Ni/Pd/Au) Application • Reset circuit of Pch, Nch, CMOS, microcomputer, CPU and MCU, Reset of logic circuit, Battery check circuit, switching circuit back-up voltage, level detecting circuit, waveform shaping circuit, delay waveform generating circuit, DC/DC converter, over voltage protection circuit Recommended Operating Condition • Supply voltage range: 2 V to 17 V Outline and Article Indication • RNA51953A, B Y : Year Code (the last digit of year) M : Month Code W : Week Code C : Control Code Lot No. Trace Code Pin No.1 SOP-8 R 9 5 3 B YMWC CCC Type No. R 9 5 3 A YMWC CCC |
