ISL88011IH544Z-TK

Supervisors Overview

The ISL88011IH544Z-TK is a single-channel voltage supervisor IC manufactured by Renesas Electronics Corporation. It operates within an ambient temperature range of -40°C to 85°C and is housed in a 5-lead SOT-23 package (SC-74A/SOT-753). The device features a fixed input voltage threshold of 4.45V, ensuring precise monitoring for power supply integrity. It provides a minimum reset timeout of 200ms and supports both open-drain and push-pull output configurations with selectable active-high or active-low reset signals.

Supervisors Feature Summary

• Supports dual voltage monitoring or watchdog timer functionality
• Features adjustable power-on reset timing
• Offers configurable open-drain or push-pull outputs

Supervisors Applications

• Industrial controls
• Battery management systems
• Portable equipment power supervision

Supervisors Procurement Notes

Verify the exact suffix Z-TK against current manufacturer documentation to confirm pinout and electrical specifications. Confirm RoHS3 compliance status as required by project standards. Check for End-of-Life notices or product change notifications that may affect long-term availability. Ensure the selected package variant matches the PCB footprint requirements.

Supervisors Selection Notes

Select this component when a fixed 4.45V threshold is required for system supervision. Consider the 200ms minimum reset delay for circuit stability requirements. Evaluate the need for watchdog capabilities versus simple power-on reset functions. Verify compatibility with the target microcontroller's input logic levels for the chosen output configuration.

Supervisors Part Context

This part belongs to the ISL88011-ISL88015 family of voltage supervisors from Renesas. These devices are designed for low-power applications requiring reliable power management. The ISL88011 specifically targets applications needing a higher voltage threshold compared to other variants in the series.

Supervisors Replacement Considerations

ISL88011IH546Z-T7A is listed as an alternative packaging option for the same functional core.
