ISL88708IP844Z

Supervisors Overview

The ISL88708IP844Z is a single-channel microprocessor supervisor circuit manufactured by Intersil (Renesas). It operates within a supply voltage range of 2 V to 5.5 V, with a rated voltage of 5 V. The device features an adjustable power-on reset threshold and includes a watchdog timer, power-fail comparator, and manual reset functionality. It is housed in an 8-lead Small Outline package (SOIC) with a 1.27 mm pin pitch. The component supports surface mount installation and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault detection
• Provides adjustable power-on reset threshold monitoring
• Includes a dedicated power-fail comparator for voltage supervision

Supervisors Applications

• Microprocessor system power supply monitoring
• Battery function supervision in embedded systems
• Industrial control unit reset management

Supervisors Procurement Notes

Verify the specific suffix IP844Z against official Renesas documentation to confirm pinout and functional configuration. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm RoHS compliance status for the specific manufacturing lot. Validate that the operating temperature range meets the environmental constraints of the final assembly.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog and power-fail capabilities is required. The adjustable reset threshold allows customization for various rail voltages. The SOIC-8 package offers a compact solution for space-constrained designs. Verify that the 2 V to 5.5 V input range aligns with the monitored power rail specifications.

Supervisors Part Context

The ISL88708 belongs to a family of microprocessor supervisors designed for high accuracy and low power consumption. This series monitors power-supply and battery functions in microprocessor systems. The IP844Z variant specifically denotes the plastic SOIC package option within the broader ISL8870x product line managed by Intersil and Renesas.

Supervisors Replacement Considerations

Cross-reference with ISL88708IB844Z for leaded PDIP alternatives or other ISL8870x variants with matching thresholds. Verify electrical equivalence before substitution.
