PMIC - Supervisors: MCP1316T-32LE/OT Application Field and Working Principle

PMICs, or power management integrated circuits, are integrated circuits designed to improve the performance, power efficiency, and power management of a variety of components, such as microprocessors, memory, I/O devices, and other consumer electronics. They are divided into several categories, including voltage regulators, DC/DC converters, LED driver controllers, and supervisors. Supervisors are employed to detect and monitor power levels, as well as reset circuits to prevent misuse or damage from overloading, over-voltage, or other fault conditions. In this article, we will focus on the MCP1316T-32LE/OT Power Supervisor, a device created by Microchip Technology.The MCP1316T-32LE/OT Power Supervisor is a microcomputer-compatible supervisor with an industrially-hardened operating range from -40°C to +125°C. It includes an open-drain active-low reset output and LOW, MIN, and MAX thresholds for either 3.3 V or 4.4 V. The LOW threshold prevents unintentional power-up sequencing, the MIN threshold provides reset during low-voltage fault conditions, and the MAX threshold sets the upper limit of the input power level.The MCP1316T-32LE/OT is capable of sensing over-voltage and under-voltage conditions in three ways: with a built-in voltage divider, with an external connection, or with an internal reference. When an over-voltage or under-voltage condition is detected, an active-low reset output is asserted. In addition, the MCP1316T-32LE/OT also provides timer reset and system reset functions, as well as an active-high reset output that can be enabled by an input pin.The MCP1316T-32LE/OT is suitable for a wide variety of applications, including automotive, communication and computing, industrial, and healthcare. It is a popular choice in automotive applications, such as power steering, airbag, and AUX systems, due to its high accuracy and wide operating temperature range. It is also suitable for industrial applications that require voltage regulation, over-voltage protection, and reset functions, such as solar power systems and control circuits.The MCP1316T-32LE/OT is supplied in a variety of package formats, including PDIP, SOIC, QFN, TSOP, and VQFN. The device is powered by a 2.7V to 5.5V voltage supply and features an ultra-low operating current of 2 µA. Its RDS(ON) value is low (24 mΩ), making it suitable for direct connection to a power source.In conclusion, the MCP1316T-32LE/OT Power Supervisor is a highly accurate and versatile device that can be used in a variety of applications. It is particularly suited to automotive and industrial applications where over-voltage and under-voltage conditions must be detected, as well as reset and timer functions are needed. Its wide operating temperature range and low operating current make it an ideal choice for these applications.
