ISL88012IH523Z

Supervisors Overview

The ISL88012IH523Z is a dual-channel voltage supervisor in a SOT-23-5 package. It features adjustable power-on reset (POR) with a typical delay of 250 ms and supports manual reset input. The device monitors two independent voltage rails, offering configurable active-high or active-low outputs. It operates within a supply range up to 5.5 V and includes an integrated watchdog timer option. Operating temperature spans -40°C to +85°C.

Supervisors Feature Summary

• Dual voltage monitoring capability for independent rail supervision
• Configurable output polarity supporting active-high and active-low modes
• Integrated manual reset input for system control flexibility
• Adjustable power-on reset timing with standard 250 ms delay

Supervisors Applications

• Portable electronic devices requiring dual-rail supervision
• Industrial control systems needing reliable power monitoring
• Communication equipment ensuring stable voltage levels
• Automotive electronics operating in extended temperature ranges

Supervisors Procurement Notes

Verify the specific suffix 'H523' against the manufacturer's current datasheet to confirm threshold voltages and pinout compatibility. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the package marking with official Renesas/Intersil identification guides to prevent counterfeit parts during sourcing.

Supervisors Selection Notes

Select this component when dual-channel supervision is required in a compact SOT-23-5 footprint. It is suitable for designs needing adjustable POR delays and manual reset functionality. Consider alternative models if single-channel monitoring suffices or if higher voltage thresholds are necessary beyond the standard 5.5 V limit.

Supervisors Part Context

Part of the ISL8801x series from Intersil, now under Renesas Electronics. This family provides versatile voltage supervision solutions for portable and industrial applications. The ISL88012 specifically addresses dual-monitoring needs, distinguishing itself from single-channel variants like the ISL88011.

Supervisors Replacement Considerations

Check for ISL88011 variants if only one channel is needed. Verify ISL88013 equivalents if a built-in watchdog timer is preferred over external configuration. Ensure package compatibility with SOT-23-5 footprints before substitution.
