Power Management IC (PMIC) supervisors serve a range of applications, including monitoring a variety of input voltages, providing reset signals for system start-up, and providing comparable factory programmable delays for supervision control. The MAX810LTRG is an integrated power management IC supervisor from Maxim Integrated. As a PMIC supervisor, it provides the power supply necessary to power IC microprocessors and advanced microcontrollers, facilitating their operation. The MAX810LTRG provides a functional range of high accuracy, low power operation and high integration for supervisors. The MAX810LTRG consists of three main parts: a power supply controller, supervisor circuit, and timing circuits. All components run off the same voltage supply, so no external components are needed for basic operation. The power supply controller builds up a power line circuit and produces monitored and adjustable voltage output, monitoring supply voltages and providing diagnostic information in the event of an under voltage or over voltage condition. This controller supports operation down to +2.2V, with adjustable output. The main supervising circuit blocks occur between Device Under Test (DUT) and power supply output. The MAX810LTRG utilizes two different blocking methods, i.e. voltage monitor and voltage trip. Voltage monitor supervises the voltage level of the DUT and sends out a reset signal when the voltage drops below a certain level. This is generally used for low power applications and for start-up applications. The Voltage Trip supervises the DUT, threshold in the DUT rising above a certain level, then sends out a reset signal. This is used for applications where a voltage on the DUT must always remain within a certain range and ensures that power is supplied to the DUT within a certain margin of safety.The MAX810LTRG also includes three timing circuits, each with a variety of configurations to set delays from microseconds (µs) to hours (h), depending on the application. In addition, the MAX810LTRG allows a power-fail detector and voltage reference to be connected externally, giving additional flexibility.The MAX810LTRG provides both low-voltage and over-voltage protection, as well as manual reset, delay-on-force reset and a watchdog timer feature, allowing multiple system delay configurations. It also has an LED output feature that makes signal status visible by changing LED source brightness. The MAX810LTRG is designed to provide maximum system flexibility and accuracy in power supply applications. It has a wide input voltage range of +2.2V to +18V, and is able to supply up to 10mA output current. It also enables reset options down to 0.53µs time delay, and can be programmed to reset on rising and falling signals.The MAX810LTRG provides for a more stable power supply as compared to most linear regulators. With its wide input voltage range, adjustable output voltage and independent power supply, the MAX810LTRG can be used in various applications, such as automotive, industrial, computer, networking, and personal video recorders. It is a low power consumption solution suitable for both high-volume and low-volume applications where accuracy and reliability are essential.
