PMIC - Supervisors: TCM811MERCTR Application Field and Working Principle

The TCM811MERCTR is an exceptionally versatile Supervisory circuit that can provide intelligent control for a variety of tasks. It is a chip designed for use on board microprocessor related system boards to monitor power supply, output and input voltages. It is a common choice for applications in industrial, automobile (ECU), communications, consumer electronics and medical. This Supervisor circuit has several features including under voltage monitoring, reset generation, over voltage and power fail protection. The chip runs on 3.3V and 5.0V supplies and supports 8-bit and 16-bit microprocessors. It has an adjustable reset threshold voltage. It has a high level of accuracy and is available in several package sizes including 8-pin SOIC and 8-pin PDIP.The basic working principle of the TCM811MERCTR chip is to monitor the input voltage and compare it to an adjustable reference voltage. The reference voltage is the reset threshold voltage. When the input voltage rises the reference voltage will also increase until it reaches to predetermined set value at which point a reset pulse will be generated.The chip can be used to monitor variety of input voltages including 3.3V, 5.0V and 12V. The reference voltage (or reset threshold voltage) can be set from 0.9V to 5.0V. The reset generator can generate reset pulses from 50us to 250ms. The chip has a built-in power fail detector that monitors the incoming power supply and generates a reset signal when the power supply is lost.The TCM811MERCTR can be used to protect the system from low voltage, over voltage and power fail situations. The chip can be used in a variety of applications including industrial, automotive, communications, consumer electronics, and medical applications. The TCM811MERCTR is a versatile solution as it provides intelligent control, accurate threshold voltage and adjustable reset pulse duration. These features along with its wide range of application field make it a highly reliable and popular solution for supervisors.
