ISL88012IH546Z-TK

Supervisors Overview

The ISL88012IH546Z-TK is a dual-channel voltage supervisor IC from Renesas Electronics Corporation, designed for multi-voltage monitoring applications. It features open-drain and push-pull outputs to provide flexible reset signaling. The device monitors two distinct voltage rails with a minimum reset timeout of 140ms. It operates within a standard temperature range and is housed in a compact 5-SOT package. This component ensures system reliability by detecting out-of-range conditions and initiating appropriate reset sequences.

Supervisors Feature Summary

• Dual-channel voltage monitoring capability for supervising multiple power rails simultaneously
• Flexible output configuration supporting both open-drain and push-pull reset signals
• Configurable power-on reset timeout to accommodate specific system startup requirements

Supervisors Applications

• Multi-rail power supply monitoring in industrial control systems
• Voltage supervision for embedded computing platforms
• System reset management in telecommunications equipment

Supervisors Procurement Notes

This part number is officially listed as obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of current availability should focus on authorized distributors holding remaining stock or approved substitute components. Ensure any replacement parts meet the original electrical specifications and pin compatibility before integration into existing designs.

Supervisors Selection Notes

Engineers selecting this component should note its dual-channel architecture suitable for systems requiring simultaneous supervision of two voltage levels. The combination of open-drain and push-pull outputs offers design flexibility for interfacing with various logic families. Consider the 140ms minimum reset timeout when designing circuits sensitive to power-up sequencing delays.

Supervisors Part Context

The ISL88012 belongs to the ISL8801x series of voltage supervisors, which are designed for reliable power management in electronic systems. These devices typically integrate precision comparators and timers to detect voltage anomalies. The series supports various package options and threshold voltages to suit different application needs across consumer, industrial, and automotive sectors.

Supervisors Replacement Considerations

Publicly confirmed substitutes include similar dual-channel supervisors such as the MIC2777-46YM5. Verify that replacement candidates match the original's voltage thresholds, output types, and package dimensions to ensure seamless integration without redesigning the PCB layout.
