Power management IC (PMIC) supervisors are commonly used in various applications. A PMIC supervisor consists of voltage monitoring and logic circuits that monitor power-on reset and other reset conditions, such as brown-out protection and power sequencing. The MAX6757UTLD3+ is a supervisor IC which is designed and intended for use in applications that require voltage monitoring.
The MAX6757UTLD3+ offers a wide input voltage range of 0.8V to 5.5V and can monitor up to four different voltages, allowing it to be universal for various applications. The MAX6757UTLD3+ has a low supply current of typically 0.5µA in active mode to minimize the overall power consumption of the system. It also includes two open-drain outputs for indicating power-on reset (POR) and other reset condition status. The POR output has an active-low reset with a POR timeout from 10ms to 500ms.
The MAX6757UTLD3+ provides selectable supply power-on reset (POR) thresholds from 1.2V to 3.2V in 0.2V increments. The low-voltage detection threshold is adjustable from 0.8V to 1.1V in 0.1V increments and the MAX6757UTLD3+ can be used to monitor many types of voltage transients such as brown out, over-voltage, under-voltage, and power sequencing. It also features a power-on delay of up to 50ms after power-on reset and can be triggered by a number of events such as voltage initiation, voltage falls below the blanking threshold, a system reset, or a combination of the above events. The MAX6757UTLD3+ can be used in a range of applications, including industrial and automobile electronics, hand-held power supplies, portables systems and general power management.
Working Principle of MAX6757UTLD3+
The MAX6757UTLD3+ is a voltage monitoring device that monitors up to four supply voltages and outputs a logic active-low reset to the system whenever any of them fall below the monitored thresholds. The MAX6757UTLD3+ also has two open-drain power-on reset outputs; a POR output and a LVR output. The POR output is activated when the monitored voltages exceed the POR threshold. The POR threshold can be adjusted between 1.2V and 3.2V with 0.2V increments. The LVR output is used to indicate when there is a low-voltage condition, and the threshold is adjustable between 0.8V and 1.1V with 0.1V increments.
When the monitored voltage falls below the programmed threshold, the POR and LVR outputs are driven low to indicate the active low-voltage status. The POR output has a timeout of up to 500ms to reset the POR signal after the voltage is restored above the POR threshold. This timeout can be adjusted between 10ms and 500ms, allowing more flexibility to the user, as applications may vary in terms of the power-on sequences or any other conditions that need to be taken in to account. The MAX6757UTLD3+ also includes a power-on delay of up to 50ms to ensure that the voltage is stabilized before the POR and LVR signals are activated.
The MAX6757UTLD3+ works with a wide input voltage range of 0.8V to 5.5V and can be used to monitor a number of voltage transients, such as brown out, over-voltage and under-voltage, making it suitable for a range of applications. Furthermore, its low power consumption, selectable POR thresholds, adjustable voltage detection thresholds, low-voltage response time, and timeout make the MAX6757UTLD3+ an ideal choice for monitoring supply voltages in applications requiring precision and reliability.
Application Field Of MAX6757UTLD3+
The MAX6757UTLD3+ has a wide range of applications, including industrial and automobile electronics, hand-held power supplies, portables systems and general power management. It can be used in any application that requires voltage monitoring and reset in order to ensure optimal system performance.
The MAX6757UTLD3+ is an ideal solution for applications such as mobile phones, navigation systems, digital still cameras, and automotive safety systems, as these applications require precise voltage monitoring and reset signals. The MAX6757UTLD3+ can also be used in applications such as electric vehicles, solar energy systems, automotive batteries, and motor control systems, which require higher precision and reliability.
The MAX6757UTLD3+ is also suitable for use in consumer electronics such as portable media players, digital cameras and camcorders, as well as handheld gaming consoles and medical devices. These applications require precise voltage monitoring and reset signals for their safety, reliability, and performance.
In conclusion, the MAX6757UTLD3+ is a versatile voltage monitoring IC that is suitable for a wide range of applications. With its extensive range of features, such as adjustable POR thresholds and adjustable low-voltage detection thresholds, the MAX6757UTLD3+ is an ideal solution for applications that require precise voltage monitoring and reset signals.
