ISL8702IBZ-T is a member of Intersil\'s PMIC - Supervisors family, which provides positive and negative supervisors with a windowed watchdog and reset generator to provide protection for microprocessors and MCUs. The ISL8702IBZ-T has a wide variety of applications in both industrial and consumer electronic applications such as hard disk drives, printers, automotive, access control systems, and communications.

The ISL8702IBZ-T supervises two power systems, providing independent windowed-watchdog and reset generators for each power system. These two systems can be configured as two independent power supplies or as a single supply with two outputs.

The ISL8702IBZ-T provides IPMI compliance to protect against miscellaneous reset sources. It features an integrated manual reset button, active-low reset/power-on reset output, and watchdog timeout reset/NMI output with a programmable timeout up to 255.5 seconds. The reset signal includes an externally configurable, four-level reset assertion delay, which strengthens the reset sequencing resolution.

The ISL8702IBZ-T can identify both under-voltage and over-voltage conditions. It also provides fault protection against an over-temperature event that can be set within a range of 145c to 205c. The device automatically switches off the load upon detection of an over-temperature fault, and can drive logic-level signals for system shutdown.

The ISL8702IBZ-T also features a built-in programmable watchdog timeout that monitors system activity. This watchdog timeout can be configured to generate a reset signal or an NMI interrupt. The device also has an integrated manual reset button and Input Protection that allows manual action reset and safe protection against sourcing current.

The ISL8702IBZ-T also allows for safe start-up power sequencing when used with a complex system. This device is compatible with PMBus, providing a range of system monitoring, including power-on and power-off sequencing, total-system power delivery measurements, and on/off regulation.
