ISL88012IH544Z-TK

Supervisors Overview

The ISL88012IH544Z-TK is a dual-channel voltage supervisor integrated circuit manufactured by Renesas Electronics Corporation. It provides monitoring for two independent voltage rails with adjustable thresholds, ensuring system integrity during power fluctuations. The device features an open-drain and push-pull output configuration to support various logic families. Designed for robust industrial applications, it operates within a temperature range of -40°C to +85°C. The component includes a minimum reset timeout of 140ms to prevent premature resets during power-up sequences. It is housed in a compact 5-pin SOT-23 package, suitable for surface-mount assembly.

Supervisors Feature Summary

• Dual-channel voltage monitoring with individually adjustable thresholds for precise power supervision
• Versatile output stage combining open-drain and push-pull capabilities for flexible interface compatibility
• Guaranteed minimum reset timeout duration ensures stable system initialization during power-on events

Supervisors Applications

• Industrial control systems requiring reliable power supervision
• Embedded systems needing multi-rail voltage monitoring
• Consumer electronics demanding compact power management solutions

Supervisors Procurement Notes

Verify component authenticity through authorized distributors as the part may be subject to obsolescence notices. Confirm current availability status prior to ordering since production lifecycle changes can impact supply continuity. Ensure packaging specifications match project requirements for surface-mount integration. Cross-reference datasheet revisions to confirm pinout and electrical parameter consistency with existing designs.

Supervisors Selection Notes

Select this component when dual-vail supervision is required in space-constrained designs. The adjustable threshold feature allows customization for specific rail voltages without external resistors. Consider the combined open-drain and push-pull output for interfacing with diverse microcontroller inputs. Evaluate thermal performance within the specified operating range for long-term reliability in varying environmental conditions.

Supervisors Part Context

This supervisor IC belongs to the ISL8801x series from Renesas, which offers single and dual-channel monitoring solutions. The series is designed for applications requiring simple yet effective power management. Similar parts in the lineup include variants with different channel counts or fixed thresholds. The technology leverages Intersil heritage for high-reliability analog monitoring functions.

Supervisors Replacement Considerations

Check for direct substitutes within the ISL8801x family that offer compatible pinouts and electrical characteristics. Verify if alternative dual-channel supervisors meet the specific threshold adjustability and output drive requirements. Ensure any replacement maintains the same package footprint and operating temperature range for seamless integration.
