Power management integrated circuit (PMIC) is a multifunctional integrated circuit which works to control, monitor and regulate the power flow in an integrated circuit. Supervisory circuits (also known as supervisor IC) are a key component of PMICs that protect the system by monitoring and regulating power. The MAX16012TT+T application field and working principle are focused on supervisory circuit functions, which are very helpful in power management.

MAX16012TT+T Overview

The MAX16012TT+T is a high-performance, low-power voltage supervisor designed to safely monitor system power and signal accuracy. It features two independent low-power, high-accuracy voltage references, with two independent output voltage thresholds for each reference. The device is also a continual voltage supervisor and includes an adjustable power-on reset delay and active-low reset output.

The MAX16012TT+T offers a wide input supply range of 1.8 V to 5.5 V and accepts a variety of voltage signals (including both buffered and unbuffered inputs) to protect and detect voltage variation, so that power is only provided when sufficient levels are detected. Additionally, the MAX16012TT+T features active-low, open-drain output mode, power-on reset and output flags reset time-out feature, sequential testing of multiple supply voltages, and programmable reset assertion thresholds.

Applications of MAX16012TT+T

The MAX16012TT+T is a voltage supervisor that can be used in a variety of applications. It is suitable for providing reset in embedded systems or as a supervisory circuit for power-on reset and system wake-up in digital electronic systems. The device can be used for voltage monitoring and power-on reset components in systems that require low power, high accuracy, and small size. For example:

• Portable battery powered devices.
• Vehicle power systems.
• Telecommunication systems.
• Distributed power systems.
• Battery management systems.
• Medical systems.

How MAX16012TT+T Works

The MAX16012TT+T monitors the power supply voltage (VCC) and can be programmed to assert an active-low reset signal. The device features an adjustable power-on reset (POR) delay, which is used to extend the active-low reset assertion time. Additionally, the device contains two independent voltage references with two independent output thresholds for each reference. It also features a power-on reset and output flags reset time-out feature, sequential testing of multiple supply voltages, and programmable reset assertion thresholds.

The voltage supervisor continuously monitors the input voltage through the VCC pin. If the voltage supplied to the VCC pin drops below the set threshold value, the device will assert an active-low reset signal. This reset signal will hold until the supply voltage rises above the set threshold. The device also features a sequencer mode, which allows the user to sequentially test multiple supply voltages.

Conclusion

The MAX16012TT+T is a high-performance, low-power voltage supervisor designed to safely monitor system power and signal accuracy. It can be used as reset circuit in embedded systems or as a supervisory circuit for power-on reset and system wake-up in digital electronic systems. The device features two independent low-power, high-accuracy voltage references, with two independent output voltage thresholds for each reference, adjustable power-on reset delay, active-low reset output, and power-on reset and output flags reset time-out feature. The MAX16012TT+T is suitable for providing reset in a variety of applications, such as portable battery powered devices, vehicle power systems, telecommunication systems, distributed power systems, battery management systems, and medical systems.
