ISL8700IBZ

Supervisors Overview

The ISL8700IBZ is a four-channel power supply monitor, tracker, and sequencer manufactured by Renesas Electronics Corporation. It operates within a voltage range of 2.97V to 5.5V and supports an operating temperature range from -40°C to +85°C. The device is housed in a 16-lead TSSOP package with an exposed pad. Key electrical parameters include a typical reset delay time of 1ms and a watchdog timer timeout of 140ms. It features independent channel control for precise power management sequencing.

Supervisors Feature Summary

• Provides independent monitoring and tracking for up to four power rails
• Supports configurable power-up and power-down sequencing sequences
• Integrates a watchdog timer with programmable timeout functionality
• Includes open-drain reset outputs for system supervision

Supervisors Applications

• Complex embedded systems requiring multi-rail power sequencing
• Industrial control units with strict power management requirements
• Telecommunications infrastructure equipment
• Automotive electronic control modules

Supervisors Procurement Notes

Verify the specific suffix (IBZ) against current Renesas datasheets to confirm package type and RoHS compliance status. Check for End-of-Life notices or Product Change Notifications as this component series may have limited availability. Ensure the ordering part number matches the exact pinout and thermal pad configuration required for your PCB design.

Supervisors Selection Notes

Select this component when designing systems that require synchronized power sequencing for multiple voltage rails. It is suitable for applications needing precise timing control between power rails during startup and shutdown. Consider the TSSOP package constraints and thermal dissipation requirements when evaluating board layout options for this integrated circuit.
