Power management integrated circuits (PMICs) are integral components in electronic systems, providing voltage regulation, power sequencing, and power monitoring. Among PMICs, supervisory ICs play an important role in ensuring system stability and reliability. As a member of supervisory ICs, the ADM1816-R23AKSZ-R7 has a wide range of application fields and principles. ADM1816-R23AKSZ-R7 is a low power supervisor IC from Texas Instruments, with a wide range of applications. It provides voltage supervision, reset and watchdog signals for system monitoring. It is used for battery-powered and portable devices, such as health and wearables, personal computers, automotive, industrial, and digital point-of-sales. The on-chip Functionality and Low Standby-Current make this chip suitable for low power, low standby current and cost sensitive battery-powered applications. This IC can be configured as either a single supervisory circuit or a dual supervisory circuit, providing one or two monitoring signals . The ADM1816-R23AKSZ-R7 features an adjustable threshold voltage detector, a reset output, and a watchdog timeout. The reset output can be configured as a push-pull, open drain, or manual reset output and can be used to reset the system. The watchdog timeout output can be configured as a reset or interrupt output. The IC also includes a power-on reset generator with an adjustable output delay time. The ADM1816-R23AKSZ-R7 monitors the voltage levels of power supplies. When the monitored voltage falls below the preset threshold value, the watchdog timeout output is activated. If the voltage remains low, the reset output is activated, resetting the entire system. The delay time of the reset output can be adjusted by adjusting a capacitor connected to the delay pin. The watchdog timeout output generates a timeout reset based on a user-defined time period, resetting the system unless the timeout period is reset by a frequency lower than 10Hz. The ADM1816-R23AKSZ-R7 also features an on-chip regulator, protecting the chip from over-voltage conditions. This chip also includes an on-chip set or reset switch, which allows external control of the reset pin. The device includes additional features such as reverse current blocking, programmable threshold, and thermal shutdown for superior system protection. In summary, the ADM1816-R23AKSZ-R7 is a low power supervisor IC from Texas Instruments with a wide range of applications in the battery-powered and portable devices. The device provides voltage supervision, reset and watchdog signals for system monitoring and protection with adjustable output delay time, reverse current blocking, programmable threshold, thermal shutdown and external control of the reset pin. The chip is designed for low power and low standby current to meet the requirements of battery-powered applications. The ADM1816-R23AKSZ-R7 is a low power supervisor IC from Texas Instruments, with a wide range of applications including battery-powered and portable devices, that provides voltage supervision, reset and watchdog signals for system monitoring. The chip contains a variety of features such as adjustable threshold voltage detector, adjustable output delay time, reverse current blocking, programmable threshold, thermal shutdown and external control of the reset pin for superior system protection.
