The ISL6561IRZ is an intelligent reset generator (IRG) for today’s advanced system power management applications. It is part of a family of Intelligent Reset Generator (IRG) from Intersil that includes IRG, SRG, LRG, and PRG versions. The IRG series of parts are used to provide system reset signals to restore and protect system performance in the event of any power system fault. The ISL6561IRZ is designed to be used in system power supplies or any other automotive or industrial application requiring precise management of reset conditions.

The ISL6561IRZ integrated circuit contains a voltage monitoring circuit, reset control logic, and a reset output stage in a single package suitable for a variety of power management applications. Its internal monitoring circuit is capable of monitoring the system’s input voltage, and the reset level is adjustable via internal voltage dividers. The reset control logic is designed to provide an accurate and consistent reset threshold, regardless of input voltage variation. The reset output stage is designed to deliver robust output levels in the presence of large transients.

The ISL6561IRZ is available in several packages, including SOIC-8, TDFN-8, and DFN-10 packages. All of these packages are designed to dissipate heat efficiently while providing a small footprint. The ISL6561IRZ is specified to operate over a wide temperature range of -40°C to 125°C.

The ISL6561IRZ is an ideal solution for various automotive and industrial applications, such as automotive power train systems, power converters, power supply sequencing, battery monitoring, HVAC controllers, and any other system that requires precise reset timing for proper system operation. In addition, the ISL6561IRZ provides advanced features such as watchdog support and active low ( RESET) and active high (PHASE_EN) outputs, as well as a low power standby mode.

The ISL6561IRZ’s main working principles and features include power up/down sequencing of multiple rails, correct startup and shutdown of processor cores, system reset when input voltage is outside acceptable range or whenever an over-temperature occurs, power loss detect and alert capability, precision reset delay multiple of 16.3ms, and early warning signal in case of incorrect startup sequence. It also integrates a watchdog timer which allows the system to detect any failure or cause of system and take appropriate action, such as assert the reset output. It has an active high ( PHASE_EN) and active low ( RESET) output type.

The ISL6561IRZ provides a wide range of application fields such as automotive, industrial, and embedded systems. It can also be used for different types of power supplies and any other power management system requiring precise management of reset signals. It is ideal for applications where accurate reset timing is required, such as battery monitoring, HVAC controllers, power supply sequencing, and so on. The ISL6561IRZ also offers other features, such as fast and reliable initialization, programmability, low standby current, and robust reset timing.

In summary, the ISL6561IRZ is a powerful power management tool that offers precise reset timing, protection from incorrect startup sequences, and accurate input voltage monitoring. Its wide range of applications, robust reset timing, and wide temperature range make it an ideal solution for many different industrial and automotive applications. It is a reliable, flexible and cost-effective option for power management applications.
