ISL88031IUHFZS2711

Supervisors Overview

The ISL88031IUHFZS2711 is a multi-voltage supervisor IC manufactured by Renesas Electronics Corporation. It features five monitored voltage channels with open-drain or open-collector outputs and active-low reset signals. The device includes a minimum reset timeout of 80ms. Thresholds are specified at 3.078V and 4.634V for two channels, while three channels offer adjustable thresholds. It operates within a temperature range of -40°C to 85°C (TA) and is housed in an 8-MSOP package.

Supervisors Feature Summary

• Provides supervision for up to five independent voltage rails simultaneously
• Features configurable threshold monitoring for flexible system protection
• Delivers active-low reset signals via open-drain or open-collector outputs

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Voltage supervision for microprocessor and FPGA boards
• Industrial control unit power integrity verification

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to the End-of-Life status indicated in public records. Confirm that the specific suffix matches required pinout and electrical specifications. Check RoHS compliance documentation for environmental adherence. Validate package integrity upon receipt as surface-mount components are sensitive to handling damage.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage domains is required within a compact footprint. Ensure the adjustable threshold capability aligns with specific rail requirements. Verify that the 80ms minimum reset timeout meets system startup timing constraints. Confirm compatibility with the target logic voltage levels supported by the open-drain output structure.
