The ISL88016IHTZ-T7Ais an advanced supervisor that is designed to monitor power voltage rails in products such as computers, consumer electronics, and industrial equipment. It features both microprocessor/microcontroller supervisor and power-on reset (POR) functions. This device is used to provide reliable power-on reset and monitoring of system power conditions. It is a cost effective solution that is able to monitor and supervisory multiple low power rails while preventing the device from becoming over-current, or short-circuited.

Overview

The ISL88016IHTZ-T7A monitoring and supervisory device can operate in five different low voltage rail regimes. It supports voltage levels for Microprocessor, 3.3V, 2.5V, 1.8V and 1.5V. The independent POR and reset outputs are user-programmable for 1.2V output voltage level. The device also features single-cycle power-on reset, under voltage and over voltage detection, power control circuitry, sequential power control with power-on reset feature, adjustable minimum and maximum reset timings, and adjustable reset timeout.

The ISL88016IHTZ-T7A is also designed to provide accurate real-time power monitoring and system supervision. The monitoring circuit consists of four analog comparators, two low voltage detect comparators and two high voltage detect comparators. The low voltage detect monitors the voltage rail level and triggers an alarm if it falls below the programmed minimum range. Similarly, the high voltage detect comparators monitor the voltage rails and triggers alarms when it exceeds the set upper limit. The device also incorporates a Fault Mode Timer to provide fast system shutdown.

Application Field

The ISL88016IHTZ-T7A is a versatile device and has a wide range of applications. It is suitable for systems that require reliable power monitoring and control. It can be used in systems that use single and multiple power rails, such as personal computers, portable devices, industrial systems and automotive applications. The device is also suitable for distributed power systems that require voltage rail supervision and power-on reset functions.

The device is designed to provide reliable power-on reset, under voltage and over voltage detection, and adaptive power management. It is widely used in desktop and mobile PC Motherboard applications, processor power supply systems and industrial equipment. The device is also suitable for low-cost remote control systems, electronic gaming consoles, and automotive secondary power domains.

Working Principle

The ISL88016IHTZ-T7A is a voltage supervisor and power-on reset (POR) device. It includes power-on reset circuitry with adjustable maximum and minimum reset timings, as well as adjustable reset timeout. The device also includes on-chip analog comparators to monitor the voltage rails and trigger alarm if the voltage level exceeds the programmed minimum or maximum range. The analog comparators are connected to a microprocessor/microcontroller that is responsible for the device’s reset and power-on functions.

The voltages detected by the analog comparators are compared to the programmed upper and lower threshold values. If the voltage level is below the lower or higher than the upper limit, an alarm is triggered. This alert signals the microprocessor to perform a system reset or power-on sequence. The device also incorporates a Fault Mode Timer that provides fast system shutdown in case of failure.

The ISL88016IHTZ-T7A is a reliable device with a wide range of applications. It can be used in systems with multiple power rails, ranging from microprocessor to 1.5V levels. The device provides reliable power-on reset and monitoring of system power conditions. It also features adjustable reset timeout and allows for fast system shutdown in case of voltage failure. The device is a cost effective solution that is suitable for a wide range of applications.
