Introduction

ADM1232ARMZ-REEL7 is an integrated, self-contained Power Management IC (PMIC) specifically designed for use in many electronic appliances. It provides precise power management, versatility and cost-effectiveness for applications including medical, industrial, automotive, computing and consumer systems. The ADM1232ARMZ-REEL7 is intended for use as a system supervisor and power manager to monitor power supply voltages and system peripherals and to provide system reset, interrupts and related functions.

Features

The ADM1232ARMZ-REEL7 includes several features to enable easy integration into an existing system, including:* Digital reset output: Power-on reset from manual reset using built-in safety circuits* Programmable reset timeout with internal and external reset sources for improved system reliability* Programmable brownout and overvoltage protection* Four digital outputs for high immunity to noise* Power-up, power-down delays for system reset* Programmable open-collector or push-pull outputs* Interrupt request/acknowledge with active edges and periods* Temperature sensor* Low operating doe – less than 5 μA typical

Application Fields

The ADM1232ARMZ-REEL7 is particularly suited to applications and markets where robust power management and reliable system supervision are needed. The device is designed to be the first defence against voltage discrepancies that could cause system instability or even system shutdown. The ADM1232ARMZ-REEL7 is ideal for use in a range of application areas, including medical, industrial, automotive and consumer electronics. The integrated voltage monitor and reset functions are well suited to these applications, ensuring that the system remains stable even in extreme conditions. The low-power consumption of the device makes it suitable for applications that require low-power consumption, such as mobile devices and portable devices. The device’s digital reset output and programmable reset timeout provide a very high level of system reliability and make it ideal for use in critical applications, including medical equipment and aerospace systems.

Working Principle

The ADM1232ARMZ-REEL7 is a highly integrated PMIC that combines power management and system supervision in a single device. The device actively monitors the supply voltage to ensure that the voltage levels remain within preset limits during various scenarios. For example, if the supply voltage begins to vary beyond normal parameters, the device can either shut down the system or emit an interrupt signal to warn the system of an abnormality. In addition to monitoring supply voltage, the ADM1232ARMZ-REEL7 can also detect overvoltage and brownout conditions, as well as active edges and periods. This can help to prevent system instability and system shutdown due to transient voltage spikes. The adjustable power-up and power-down delays of the device make it ideal for applications where rapid system startup and shutdown is required. The built-in temperature sensor is also included to ensure that the device does not overheat, an important factor for many applications.

Conclusion

The ADM1232ARMZ-REEL7 is a highly reliable PMIC – Supervisors that provides superior power management and system supervision capabilities for a wide range of application areas, from medical to automotive and consumer electronics. It is ideally suited for applications that require robust monitoring and reliable system control, offering adjustable power-up and power-down delays as well as temperature sensing. By monitoring the supply voltage for discrepancies and responding quickly to any anomalies, the ADM1232ARMZ-REEL7 can help preserve the integrity of sensitive systems and ensure the safety and continuity of operations in mission-critical applications.
