MCP1501T-20E/CHY is a voltage reference product from the PMIC (power management integrated circuit) family. It is designed for applications that require precise voltage references for power supplies, and for other applications such as temperature and pressure regulation. The MCP1501T-20E/CHY voltage reference is a monolithic CMOS integrated circuit (IC) that integrates both a reference output and a reference input. The reference input is used for supervisory detection of low voltage levels or for the generation of an analog reference voltage. The MCP1501T-20E/CHY has two main application fields. The first is power supply design, where the voltage reference is used to set the output voltage of a regulator. The reference provides a precise voltage output that is immune to power supply ripple and line variations. The second application field is temperature and pressure sensing. The reference can be used to detect flucations in either temperature or pressure, and provide a feedback signal to regulate the system parameters. The MCP1501T-20E/CHY uses the bandgap reference principle, which is an integral part of any integrated circuit. In essence, the bandgap principle is based on the fact that the absolute temperature of an IC is determined by the ratio of two voltages which are generated from two reference junctions. This principle is exploited by the MCP1501T-20E/CHY IC to provide a precise voltage reference output. The MCP1501T-20E/CHY IC is designed for applications with stringent accuracy requirements and power constraints. It offers an accurate, low-drift output voltage of 1.25V over a wide range of operating temperatures. The I-PIPE output current is tight, highly linear and consumes very low power. The reference voltage can also be adjusted using an external resistor, allowing the designer to tailor the output voltage to fit their application. The MCP1501T-20E/CHY is also highly power efficient. It has a low quiescent current of typically 10uA, which can be further reduced by shutting down the reference output. The IC also features a low voltage detection circuit, which helps regulate against overvoltages and undervoltages. In summary, the MCP1501T-20E/CHY is a high-performance, low-power voltage reference IC, with applications spanning power supply design, temperature and pressure sensing, and other precision analog control systems. Its accurate and low-drift output voltage, high linearity and low power performance make it an attractive choice for applications that require precision voltage references.
