ADM6348-46ARTZ-R7, a PMIC - Supervisors device developed by Analog Devices, is a multi-channel DC/DC monitor and power-on/off reset controller that protects many system buses and power rails in personal computers, servers and communications equipment. This device automatically combines an adjustable overvoltage monitor with a wide-range voltage supervisor and an adjustable latching power-on reset circuit.

The ADM6348-46ARTZ-R7 is designed to be programmed to monitor supply voltages from 1.6V to 5.5V. It can monitor up to five supply voltages, where any voltage can be monitored for an overvoltage/undervoltage violation and/or for a power good condition. For each channel, the user can also program an output reset response time, or latch and reset or latch and ignore the violation. Set up is completed with a reliable external capacitor.

Other features of the ADM6348-46ARTZ-R7 includes allow internal programmable reset active-high or low output polarity, voltage level setting accuracy of plus or minus 10% over the full supply voltage range and a reset timeout period from 0.3 ms to 1500 ms after power-on. With its strict production process and commitment to safety, it provides outstanding and reliable performance for many DIY and industrial control applications.

The working principle of the ADM6348-46ARTZ-R7 is relatively simple. The device monitors and compares input voltage to internal voltage reference of 2.5V ± 10%. When the voltage input is higher or lower than the internal reference voltage, the device will output a reset signal. The device also has an internal RC oscillator circuit, which is set by an external capacitor, establishing a timing window during which the rising voltage must reach the internal reference voltage. In this way, the device can control the output status of the reset line.

The applications of the ADM6348-46ARTZ-R7 extent to PCs servers, consumer devices, networks and industrial products, such as power supply, HMI and digital system monitoring. In addition, ADM6348-46ARTZ-R7 also widely used in many embedded systems where a robust reset controller with an adjustable monitor and/or power-on reset time is required.

In summary, the ADM6348-46ARTZ-R7 is a reliable and versatile multi-channel voltage monitor and reset controller from Analog Devices, with strict compliance with safety regulations and excellent performance. With adjustable overvoltage monitor and adjustable latching power-on reset circuit, it provides great protection in a wide range of DIY and industrial control applications.
