ISL6536IBZ-TR5194 is listed in the Supervisors range at ChipApex. The manufacturer field lists Renesas Electronics Corporation. Its product description is IC AMP CLASS. Review the specifications below when checking this part for your BOM.
The ISL6536IBZ-TR5194 is a four-channel supervisory integrated circuit manufactured by Renesas Electronics Corporation. It is designed to monitor positive supply voltages greater than or equal to 0.7V. The device operates within an IC bias range of 2.7V to 4V and supports supervision of any positive voltage levels. It features adjustable or selectable voltage thresholds and provides open-drain or open-collector outputs with active-low reset signals. The component is housed in an 8-SOIC package (0.154 inch width) and is rated for operation between -40°C and +85°C ambient temperature. This specific part number variant is designated as obsolete and no longer in production.
This component is officially classified as obsolete and no longer in manufacturing. Verification of availability should focus on surplus distributors rather than direct manufacturer stock. Buyers must confirm the authenticity of existing inventory, as sourcing options are limited to secondary markets. Cross-referencing with current replacement parts is recommended for new designs.
Designers requiring this functionality should consider the parameter-equivalent ISL88041IBZ as a modern alternative. The original ISL6536 series lacks RoHS compliance in certain variants, whereas newer replacements may offer updated environmental standards. Engineers must evaluate pin compatibility and threshold accuracy when migrating from this obsolete four-channel supervisor to current Renesas offerings.
The ISL6536 series belongs to Renesas' legacy portfolio of multi-voltage supervisors. Originally developed under Intersil before corporate integration, these ICs provided essential protection for complex digital systems. The 'IBZ' suffix typically denotes a specific packaging and environmental compliance variant within the broader ISL6536 family, now superseded by newer generations.
The ISL88041IBZ is documented as a parameter-equivalent substitute for the ISL6536 series. Designers should verify functional equivalence regarding channel count and reset logic before implementation.
The IC is designed to monitor positive supply voltages greater than or equal to 0.7V.
Yes, the datasheet specifies that the voltage thresholds are adjustable or selectable.
