ISL88013IH544Z-TK

Supervisors Overview

The ISL88013IH544Z-TK is a single-channel voltage supervisor manufactured by Renesas Electronics (formerly Intersil). It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 4.40 V. The device provides manual reset capability, includes an integrated watchdog timer, and offers active high and active low output types. It is housed in a compact SOT-23-5 surface-mount package and supports operation across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault monitoring
• Provides configurable active high and active low reset outputs
• Supports manual reset functionality via external input

Supervisors Applications

• Industrial control systems requiring voltage supervision
• Embedded systems with watchdog requirements
• Portable equipment needing low-power monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized channels as this part is listed as End-of-Life. Confirm exact suffix specifications against official datasheets to ensure compatibility with existing designs. Check for RoHS compliance status and lead times with distributors holding remaining stock.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a 4.40 V threshold is required. Ensure the design accommodates the SOT-23-5 package constraints. Verify that the manual reset and watchdog features align with the system's safety architecture before finalizing the bill of materials.

Supervisors Part Context

This part belongs to the ISL88013 series of voltage supervisors. It shares functional similarities with other variants in the family but differs in threshold voltage and packaging options. The series is designed for general-purpose power management applications requiring reliable reset generation.

Supervisors Replacement Considerations

Direct substitutes include ISL88013IH544Z-T7A and ISL88013IH544Z-TK. Verify pinout compatibility and electrical parameters before substitution.
