S-80150ALPF-JBBTFG

The S-80150ALPF-JBBTFG is a voltage supervisor and detector circuit from Matsushita Electronics Components, designed for applications requiring power supply monitoring. This circuit offers reliable, accurate and low cost solution for establishing a power-on circuit monitor. It can monitor positive or dual power supplies, and contains an internal voltage reference and a comparator to detect the desire voltage. The circuit is composed of two main circuits, which are the monitoring circuit and the window comparator circuit. The monitoring circuit is built up of a voltage reference circuit, an amplification circuit, a comparator circuit and a reset circuit, while the window comparator circuit is constructed of a pulse amplifier circuit and an edge processing circuit. The voltage reference circuit is a bandgap voltage reference IC with an inbuilt error amplifier, temperature compensation and current limiting circuitry, which allows the circuit to track static and dynamic changes in the input voltage and provide a stable, voltage output. This voltage output is then amplified by the amplification circuit, where a voltage divider is added to limit the input voltage and provide a reference to the comparator circuit. The comparator circuit compares the amplified voltage to the voltage of the external positive or dual power supplies, and produces a comparison signal which is the output of the monitoring circuit. This comparison signal is then sent to the reset circuit where it is processed and a reset output is given. The reset output is then sent to the window comparator circuit through the reset pin. The window comparator circuit is an improved version of the traditional comparator and can detect a wide range of voltages, from 0V to 35V, in eight preset voltage regions. This circuit is much more reliable than traditional comparators and provides improved error detection. The window comparator circuit amplifies a small pulse signal and the edge processing circuit processes the input signal and releases a high or low voltage depending on the status of the input signal. The S-80150ALPF-JBBTFG can be applied in a wide range of applications requiring power supply monitoring including computer systems, industrial machines, vehicle systems and consumer electronics. It is particularly suitable for applications in which the power supply voltage needs to be monitored for more than one voltage level, as it can detect a wide range of voltages. This device also offers system designers a reliable, cost effective solution for establishing a power-on circuit monitor. Overall, the S-80150ALPF-JBBTFG is an excellent voltage supervisor and detector circuit from Matsushita Electronics Components. It is capable of monitoring positive or dual power supplies, and can detect a wide range of voltages in preset voltage regions. It is ideal for applications requiring power supply monitoring and is a reliable, cost effective solution for establishing a power-on circuit monitor.
