Peripheral elements are incorporated in a small 8-pin package, enabling peripheral circuitry to be simplified, and compact, low-cost set design to be achieved. In addition, the M62203FP has an on-chip reset circuit that monitors power supply voltage VCC (5 V) and output voltage Vout (3.3 V), enabling erroneous system operation to be prevented. Features • • • • • Wide operating power supply voltage range: 4 to 15 V (5 V Typ.) Low current dissipation: 1.0 mA (VCC = 5 V, no load) On-chip 5 V, 3.3 V dual voltage system detection reset circuitry On-chip oscillation circuit not requiring peripheral elements (110 kHz Typ.) 8-pin SOP package Applications General electronic products such as mobile and portable devices Pin Configuration (Top View) Cout1 GND Cout2 Vcc 1 2 3 4 8 7 6 5 IN1 RESET Cd IN2 Package: 8P2S-A M62203FP Rev.1.0, Sep.19.2003, page 1 of 11 M62203FP Block Diagram Vcc 4 Cd 6 IN1; 3.3V 25 µ A Reference voltage 1.25V 7 RESET comp.
