The ADM1060ARUCS0402R7 is a programmable voltage supervisor designed to provide an ultra-low power, configurable micro-controller reset solution. This device is used to monitor a power supply or other output and provide a high-accuracy reset signal with built-in programmable features. The device provides both high and low power reset as well as steady-state power sequencing, making it an ideal choice for microcontroller-based applications that require precision power-on reset.

The ADM1060ARUCS0402R7 belongs to the category of PMIC (Power Management Integrated Circuit) known as Supervisors. Supervisors are integrated circuits intended as power monitoring and protection circuits used to ensure reliable power supply performance. In general, supervisors can be used to monitor supplies, detect brown-out conditions and monitor system inputs. Also, it can provide extra features such as undervoltage lockout, reset generation and analog monitoring.

The ADM1060ARUCS0402R7 requires a single voltage source in the range of 2.3 to 5.5V. The device is operated over an ambient temperature range of -40°C to +125°C. This can be easily configured to provide either active-low or active-high reset polarity. Ultra-low power consumption (4.4μA for active-low reset polarity, 6μA for active-high reset polarity) makes this device a suitable choice for battery-powered applications that require short reset pulses.

In order to protect the microcontroller, the ADM1060ARUCS0402R7 provides a power-on reset (POR) feature. The internal POR circuit monitors an external voltage source during power-on to ensure that the microcontroller is never activated until the power has been up to a certain voltage level. This is achieved by monitoring the voltage at the VDD input pin, with a hardware reset (RST) output going low when the power-up time period is finished. The active-low RST output will remain low until the voltage at the VDD pin has stabilized within the minimum and maximum power-up thresholds.

The ADM1060ARUCS0402R7 also features a watchdog timer, which is used to prevent any code-related system failures. This timer monitors the device activity and triggers an RST output when no activity is detected for a specified duration. Additionally, the ADM1060ARUCS0402R7 provides a low-power microcontroller reset, which is useful for applications that require a power-up sequence before microcontroller activation (e.g., portable applications).

Power sequencing is managed by a single-shot pulse generator (SOAPG) of the ADM1060ARUCS0402R7. The SOAPG can be used to ensure that the power distribution has stabilized before taking any action. For instance, if the application requires a low power domain to be powered up before a high power domain, this can be easily achieved by setting the power-up and power-down intervals.

The ADM1060ARUCS0402R7 is designed to be used in many microcontroller-based applications. This IC can easily be configured to provide incorrect power-up and power-down thresholds, allowing the user to precisely manage the power-up life-cycle of the device. This device is an ideal choice for portable battery-powered applications where system reliability is key.
